Direct Known Subclasses:

FlinkCalciteSqlValidator, SqlValidatorWithSnapshot

public class SqlValidatorImpl
extends Object
implements org.apache.calcite.sql.validate.SqlValidatorWithHints

Default implementation of SqlValidator, the class was copied over because of CALCITE-4554.

Lines 1958 ~ 1978, Flink improves error message for functions without appropriate arguments in handleUnresolvedFunction at handleUnresolvedFunction(org.apache.calcite.sql.SqlCall, org.apache.calcite.sql.SqlOperator, java.util.List<org.apache.calcite.rel.type.RelDataType>, java.util.List<java.lang.String>).

Lines 3736 ~ 3740, Flink improves Optimize the retrieval of sub-operands in SqlCall when using NamedParameters at checkRollUp(org.apache.calcite.sql.SqlNode, org.apache.calcite.sql.SqlNode, org.apache.calcite.sql.SqlNode, org.apache.calcite.sql.validate.SqlValidatorScope, java.lang.String).

Lines 5108 ~ 5121, Flink enables TIMESTAMP and TIMESTAMP_LTZ for system time period specification type at validateSnapshot(org.apache.calcite.sql.SqlNode, org.apache.calcite.sql.validate.SqlValidatorScope, org.apache.calcite.sql.validate.SqlValidatorNamespace).

Lines 5465 ~ 5471, Flink enables TIMESTAMP and TIMESTAMP_LTZ for first orderBy column in matchRecognize at validateMatchRecognize(org.apache.calcite.sql.SqlCall).

Performs expression rewrites which are always used unconditionally. These rewrites massage the expression tree into a standard form so that the rest of the validation logic can be simpler.

Returns null if and only if the original expression is null.

Parameters:

node - expression to be rewritten

underFrom - whether node appears directly under a FROM clause

Returns:

Allows a subclass to provide information about how to convert an UPDATE into a MERGE via self-join. If this method returns null, then no such conversion takes place. Otherwise, this method should return a suitable unique identifier expression for the given table.

Parameters:

table - identifier for table being updated

alias - alias to use for qualifying columns in expression, or null for unqualified references; if this is equal to "SYS$SRC", then column references have been anonymized to "SYS$ANONx", where x is the 1-based column number.

Returns:

expression for unique identifier, or null to prevent conversion
