Example 26 with SqlWriter

use of org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.sql.SqlWriter in project hive by apache.

the class HiveBetween method unparse.

public void unparse(SqlWriter writer, SqlCall call, int leftPrec, int rightPrec) {
    final SqlWriter.Frame frame = writer.startList(SqlWriter.FrameTypeEnum.create("BETWEEN"), "", "");
    call.operand(VALUE_OPERAND).unparse(writer, getLeftPrec(), 0);
    writer.sep(super.getName());
    // If the expression for the lower bound contains a call to an AND
    // operator, we need to wrap the expression in parentheses to prevent
    // the AND from associating with BETWEEN. For example, we should
    // unparse
    // a BETWEEN b OR (c AND d) OR e AND f
    // as
    // a BETWEEN (b OR c AND d) OR e) AND f
    // If it were unparsed as
    // a BETWEEN b OR c AND d OR e AND f
    // then it would be interpreted as
    // (a BETWEEN (b OR c) AND d) OR (e AND f)
    // which would be wrong.
    final SqlNode lower = call.operand(LOWER_OPERAND);
