Example 1 with FilterStringGroupColGreaterStringScalar

use of org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterStringGroupColGreaterStringScalar in project hive by apache.

the class TestVectorizationContext method testStringFilterExpressions.

@Test

    ExprNodeColumnDesc col1Expr = new ExprNodeColumnDesc(String.class, "col1", "table", false);
    ExprNodeConstantDesc constDesc = new ExprNodeConstantDesc("Alpha");
    GenericUDFOPGreaterThan udf = new GenericUDFOPGreaterThan();
    ExprNodeGenericFuncDesc exprDesc = new ExprNodeGenericFuncDesc();
    exprDesc.setGenericUDF(udf);
    List<ExprNodeDesc> children1 = new ArrayList<ExprNodeDesc>(2);
    children1.add(col1Expr);
    children1.add(constDesc);
    exprDesc.setChildren(children1);
    List<String> columns = new ArrayList<String>();
    columns.add("col0");
    columns.add("col1");
