All Known Implementing Classes:: SqlAbstractConformance, SqlConformanceEnum, SqlDelegatingConformance

public interface SqlConformance

Enumeration of valid SQL compatibility modes.

For most purposes, one of the built-in compatibility modes in enum SqlConformanceEnum will suffice.

If you wish to implement this interface to build your own conformance, we strongly recommend that you extend SqlAbstractConformance, or use a SqlDelegatingConformance, so that you won't be broken by future changes.

  boolean splitQuotedTableName()
  
  Whether to split a quoted table name. If true, `x.y.z` is parsed as if the user had written `x`.`y`.`z`.
  Among the built-in conformance levels, true in SqlConformanceEnum.BIG_QUERY; false otherwise.
- allowHyphenInUnquotedTableName
  
  boolean allowHyphenInUnquotedTableName()
  
  Whether to allow hyphens in an unquoted table name.

  Among the built-in conformance levels, true in SqlConformanceEnum.BIG_QUERY; false otherwise.
- isBangEqualAllowed
  
  boolean isBangEqualAllowed()

  Note: MySQL does not support MINUS or EXCEPT (as of version 5.5).
- isApplyAllowed
  
  boolean isApplyAllowed()
  Whether CROSS APPLY and OUTER APPLY operators are allowed in the parser.
  APPLY invokes a table-valued function for each row returned by a table expression. It is syntactic sugar:
  
  SELECT * FROM emp CROSS APPLY TABLE(promote(empno)
  is equivalent to
  SELECT * FROM emp CROSS JOIN LATERAL TABLE(promote(empno)
  SELECT * FROM emp OUTER APPLY TABLE(promote(empno)
  is equivalent to
  SELECT * FROM emp LEFT JOIN LATERAL TABLE(promote(empno) ON true
  
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.ORACLE_12, SqlConformanceEnum.SQL_SERVER_2008; false otherwise.
- isInsertSubsetColumnsAllowed
  
  boolean isInsertSubsetColumnsAllowed()
  
  Whether to allow INSERT (or UPSERT) with no column list but fewer values than the target table.
  The N values provided are assumed to match the first N columns of the table, and for each of the remaining columns, the default value of the column is used. It is an error if any of these columns has no default value.
  The default value of a column is specified by the DEFAULT clause in the CREATE TABLE statement, or is NULL if the column is not declared NOT NULL.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.PRAGMATIC_99, SqlConformanceEnum.PRAGMATIC_2003; false otherwise.
- allowAliasUnnestItems
  
  boolean allowAliasUnnestItems()
  
  Whether directly alias array items in UNNEST.
  E.g. in UNNEST(a_array, b_array) AS T(a, b), a and b will be aliases of elements in a_array and b_array respectively.
  Without this flag set, T will be the alias of the element in a_array and a, b will be the top level fields of T if T is a STRUCT type.
  Among the built-in conformance levels, true in SqlConformanceEnum.PRESTO; false otherwise.
- allowNiladicParentheses
  
  boolean allowNiladicParentheses()
  
  Whether to allow parentheses to be specified in calls to niladic functions and procedures (that is, functions and procedures with no parameters).
  For example, CURRENT_DATE is a niladic system function. In standard SQL it must be invoked without parentheses:
  VALUES CURRENT_DATE
  
  If allowNiladicParentheses, the following syntax is also valid:
  VALUES CURRENT_DATE()
  
  Of the popular databases, MySQL, Apache Phoenix and VoltDB allow this behavior; Apache Hive, HSQLDB, IBM DB2, Microsoft SQL Server, Oracle, PostgreSQL do not.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.MYSQL_5; false otherwise.
- allowNiladicConstantWithoutParentheses
  
  boolean allowNiladicConstantWithoutParentheses()
  
  Whether to allow parentheses to be specified in calls to niladic functions of returned the specific constant value.
  For example, PI is a niladic function and return specific constant values pi. In standard SQL it must be invoked with parentheses:
  VALUES PI()
  
  If allowNiladicConstantWithoutParentheses, the following syntax is also valid:
  VALUES PI
  
  The same function include E which result is Euler's constant.
  Among the built-in conformance levels, true in SqlConformanceEnum.ORACLE_10, SqlConformanceEnum.ORACLE_12, SqlConformanceEnum.DEFAULT; SqlConformanceEnum.LENIENT; false otherwise.
- allowExplicitRowValueConstructor
  
  boolean allowExplicitRowValueConstructor()
  
  Whether to allow SQL syntax "ROW(expr1, expr2, expr3)".
  The equivalent syntax in standard SQL is "(expr1, expr2, expr3)".
  Standard SQL does not allow this because the type is not well-defined. However, PostgreSQL allows this behavior.
  Standard SQL allows row expressions in other contexts, for instance inside VALUES clause.
  Among the built-in conformance levels, true in SqlConformanceEnum.DEFAULT, SqlConformanceEnum.LENIENT, SqlConformanceEnum.PRESTO; false otherwise.
- allowExtend
  
  boolean allowExtend()
  
  Whether to allow mixing table columns with extended columns in INSERT (or UPSERT).
  For example, suppose that the declaration of table T has columns A and B, and you want to insert data of column C INTEGER not present in the table declaration as an extended column. You can specify the columns in an INSERT statement as follows:
  INSERT INTO T (A, B, C INTEGER) VALUES (1, 2, 3)
  
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT; false otherwise.
- isLimitStartCountAllowed
  
  boolean isLimitStartCountAllowed()
  
  Whether to allow the SQL syntax "LIMIT start, count".
  The equivalent syntax in standard SQL is "OFFSET start ROW FETCH FIRST count ROWS ONLY", and in PostgreSQL "LIMIT count OFFSET start".
  MySQL and CUBRID allow this behavior.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.MYSQL_5; false otherwise.
- isOffsetLimitAllowed
  
  boolean isOffsetLimitAllowed()
  
  Whether to allow the SQL syntax "OFFSET start LIMIT count" (that is, OFFSET before LIMIT, in addition to LIMIT before OFFSET and OFFSET before FETCH).
  The equivalent syntax in standard SQL is "OFFSET start ROW FETCH FIRST count ROWS ONLY".
  Trino allows this behavior.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT; false otherwise.
- allowGeometry
  
  boolean allowGeometry()
  
  Whether to allow geo-spatial extensions, including the GEOMETRY type.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.MYSQL_5, SqlConformanceEnum.PRESTO, SqlConformanceEnum.SQL_SERVER_2008; false otherwise.
- shouldConvertRaggedUnionTypesToVarying
  
  boolean shouldConvertRaggedUnionTypesToVarying()
  Whether the least restrictive type of a number of CHAR types of different lengths should be a VARCHAR type. And similarly BINARY to VARBINARY.
  For example, consider the query
  SELECT 'abcde' UNION SELECT 'xyz'
  
  The input columns have types CHAR(5) and CHAR(3), and we need a result type that is large enough for both:
  
  Under strict SQL:2003 behavior, its column has type CHAR(5), and the value in the second row will have trailing spaces.
  With lenient behavior, its column has type VARCHAR(5), and the values have no trailing spaces.
  
  Among the built-in conformance levels, true in SqlConformanceEnum.PRAGMATIC_99, SqlConformanceEnum.PRAGMATIC_2003, SqlConformanceEnum.MYSQL_5, SqlConformanceEnum.ORACLE_10, SqlConformanceEnum.ORACLE_12, SqlConformanceEnum.PRESTO, SqlConformanceEnum.SQL_SERVER_2008; false otherwise.
- allowExtendedTrim
  
  boolean allowExtendedTrim()
  Whether TRIM should support more than one trim character.
  For example, consider the query
  SELECT TRIM('eh' FROM 'hehe__hehe')
  
  Under strict behavior, if the length of trim character is not 1, TRIM throws an exception, and the query fails. However many implementations (in databases such as MySQL and SQL Server) trim all the characters, resulting in a return value of '__'.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.MYSQL_5, SqlConformanceEnum.SQL_SERVER_2008; false otherwise.
- allowPluralTimeUnits
  
  boolean allowPluralTimeUnits()
  
  Whether interval literals should allow plural time units such as "YEARS" and "DAYS" in interval literals.
  Under strict behavior, INTERVAL '2' DAY is valid and INTERVAL '2' DAYS is invalid; PostgreSQL allows both; Oracle only allows singular time units.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT; false otherwise.
- allowQualifyingCommonColumn
  
  boolean allowQualifyingCommonColumn()
  Whether to allow a qualified common column in a query that has a NATURAL join or a join with a USING clause.
  For example, in the query
  SELECT emp.deptno FROM emp JOIN dept USING (deptno)
  
  deptno is the common column. A qualified common column such as emp.deptno is not allowed in Oracle, but is allowed in PostgreSQL.
  Among the built-in conformance levels, false in SqlConformanceEnum.ORACLE_10, SqlConformanceEnum.ORACLE_12, SqlConformanceEnum.PRESTO, SqlConformanceEnum.STRICT_92, SqlConformanceEnum.STRICT_99, SqlConformanceEnum.STRICT_2003; true otherwise.
- isValueAllowed
  
  boolean isValueAllowed()
  
  Whether VALUE is allowed as an alternative to VALUES in the parser.
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, SqlConformanceEnum.LENIENT, SqlConformanceEnum.MYSQL_5; false otherwise.
- semantics
  
  SqlLibrary semantics()
  Controls the behavior of operators that are part of Standard SQL but nevertheless have different behavior in different databases.
  Consider the SUBSTRING operator. In ISO standard SQL, negative start indexes are converted to 1; in Google BigQuery, negative start indexes are treated as offsets from the end of the string. For example, SUBSTRING('abcde' FROM -3 FOR 2) returns 'ab' in standard SQL and 'cd' in BigQuery.
  If you specify conformance=BIG_QUERY in your connection parameters, SUBSTRING will give the BigQuery behavior. Similarly MySQL and Oracle.
  Among the built-in conformance levels:
  
  SqlConformanceEnum.BIG_QUERY returns SqlLibrary.BIG_QUERY;
  SqlConformanceEnum.MYSQL_5 returns SqlLibrary.MYSQL;
  SqlConformanceEnum.ORACLE_10 and SqlConformanceEnum.ORACLE_12 return SqlLibrary.ORACLE;
  otherwise returns SqlLibrary.STANDARD.
- allowLenientCoercion
  
  boolean allowLenientCoercion()
  Whether to allow lenient type coercions.
  Coercions include:
  
  Coercion of string literal to array literal. For example, SELECT ARRAY[0,1,2] == '{0,1,2}'
  Casting BOOLEAN values to one of the following numeric types: TINYINT, SMALLINT, INTEGER, BIGINT.
  
  Among the built-in conformance levels, true in SqlConformanceEnum.BABEL, false otherwise.
- checkedArithmetic
  
  boolean checkedArithmetic()
  
  Whether the implementation uses checked arithmetic. Most SQL dialects use checked arithmetic at runtime: they terminate with a fatal error on overflow.
