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)
.
