public final boolean isUpsert()
In SQL, this is represented using the UPSERT
keyword rather than
INSERT
; in the abstract syntax tree, an UPSERT is indicated by the
presence of a SqlInsertKeyword.UPSERT
keyword.

public void unparse(SqlWriter writer, int leftPrec, int rightPrec)
SqlNode
The leftPrec
and rightPrec
parameters give
us enough context to decide whether we need to enclose the expression in
parentheses. For example, we need parentheses around "2 + 3" if preceded
by "5 *". This is because the precedence of the "*" operator is greater
than the precedence of the "+" operator.
The algorithm handles left- and right-associative operators by giving them slightly different left- and right-precedence.
If SqlWriter.isAlwaysUseParentheses()
is true, we use
parentheses even when they are not required by the precedence rules.
For the details of this algorithm, see SqlCall.unparse(org.apache.calcite.sql.SqlWriter, int, int)
.
public void validate(SqlValidator validator, SqlValidatorScope scope)
SqlCall
The default implementation delegates the validation to the operator's
SqlOperator.validateCall(org.apache.calcite.sql.SqlCall, org.apache.calcite.sql.validate.SqlValidator, org.apache.calcite.sql.validate.SqlValidatorScope, org.apache.calcite.sql.validate.SqlValidatorScope)
. Derived classes may override (as do,
for example SqlSelect
and SqlUpdate
).
