Example 1 with AnyToVarcharParameterConverter

use of com.hazelcast.jet.sql.impl.validate.param.AnyToVarcharParameterConverter in project hazelcast by hazelcast.

the class HazelcastConcatOperator method checkOperandTypes.

@Override
public boolean checkOperandTypes(HazelcastCallBinding binding, boolean throwOnFailure) {
    HazelcastSqlValidator validator = binding.getValidator();
    for (int i = 0; i < binding.getOperandCount(); i++) {
        SqlNode operand = binding.operand(i);
        RelDataType operandType = binding.getOperandType(i);
        if (operandType.getSqlTypeName() != VARCHAR) {
            // Coerce everything to VARCHAR
            RelDataType newOperandType = HazelcastTypeUtils.createType(validator.getTypeFactory(), VARCHAR, operandType.isNullable());
            validator.getTypeCoercion().coerceOperandType(binding.getScope(), binding.getCall(), i, newOperandType);
        }
        // Set parameter converters
        if (operand.getKind() == SqlKind.DYNAMIC_PARAM) {
            int paramIndex = ((SqlDynamicParam) operand).getIndex();
            ParameterConverter paramConverter = new AnyToVarcharParameterConverter(paramIndex, operand.getParserPosition());
            validator.setParameterConverter(paramIndex, paramConverter);
