      • supportsIdentityColumns

        boolean supportsIdentityColumns()
        Does this dialect support identity column key generation?
        Returns:
        True if IDENTITY columns are supported; false otherwise.

      • supportsInsertSelectIdentity

        boolean supportsInsertSelectIdentity()
        Does the dialect support some form of inserting and selecting the generated IDENTITY value all in the same statement.
        Returns:

      • hasDataTypeInIdentityColumn

        boolean hasDataTypeInIdentityColumn()
        Whether this dialect have an Identity clause added to the data type or a completely separate identity data type
        Returns:
        boolean

      • appendIdentitySelectToInsert

        java.lang.String appendIdentitySelectToInsert​(java.lang.String insertString)
        Provided we supportsInsertSelectIdentity(), then attach the "select identity" clause to the insert statement.

        Note, if supportsInsertSelectIdentity() == false then the insert-string should be returned without modification.

        Parameters:
        insertString - The insert command
        Returns:
        The insert command with any necessary identity select clause attached.

        default java.lang.String appendIdentitySelectToInsert​(java.lang.String identityColumnName,
                                                      java.lang.String insertString)
        Provided we supportsInsertSelectIdentity(), then attach the "select identity" clause to the insert statement.

        identityColumnName - The name of the identity column
        insertString - The insert command
        Returns:
        The insert command with any necessary identity select clause attached.
