Examples with CheckConstraintCol org.apache.hadoop.hive.ql.metadata.CheckConstraint.CheckConstraintCol used on opensource projects

Example 1 with CheckConstraintCol

use of org.apache.hadoop.hive.ql.metadata.CheckConstraint.CheckConstraintCol in project hive by apache.

the class TextDescTableFormatter method getCheckConstraintRelInformation.

private void getCheckConstraintRelInformation(StringBuilder constraintsInfo, String constraintName, List<CheckConstraintCol> columns) {
    formatOutput("Constraint Name:", constraintName, constraintsInfo);
    if (CollectionUtils.isNotEmpty(columns)) {
        for (CheckConstraintCol column : columns) {
            String[] fields = new String[2];
            fields[0] = "Column Name:" + column.getColName();
            fields[1] = "Check Value:" + column.getCheckExpression();
            formatOutput(fields, constraintsInfo);
        }
    }
    constraintsInfo.append(LINE_DELIM);
}

Example 2 with CheckConstraintCol

use of org.apache.hadoop.hive.ql.metadata.CheckConstraint.CheckConstraintCol in project hive by apache.
