Direct Known Subclasses:

SqlBetweenOperator

public class SqlInfixOperator
extends SqlSpecialOperator

A generalization of a binary operator to involve several (two or more) arguments, and keywords between each pair of arguments.

For example, the BETWEEN operator is ternary, and has syntax exp1 BETWEEN exp2 AND exp3.

Method Detail

getSyntax

public SqlSyntax getSyntax()

Description copied from class: SqlOperator

Returns the syntactic type of this operator, never null.

Overrides:

getSyntax in class SqlSpecialOperator

unparse

public void unparse(SqlWriter writer,
                    SqlCall call,
                    int leftPrec,
                    int rightPrec)

Description copied from class: SqlOperator

Writes a SQL representation of a call to this operator to a writer, including parentheses if the operators on either side are of greater precedence.

The default implementation of this method delegates to SqlSyntax.unparse(org.apache.calcite.sql.SqlWriter, org.apache.calcite.sql.SqlOperator, org.apache.calcite.sql.SqlCall, int, int).

Overrides:

unparse in class SqlOperator
