Example 1 with PVarchar

use of org.apache.phoenix.schema.types.PVarchar in project phoenix by apache.

the class LikeExpression method evaluate.

@Override
public boolean evaluate(Tuple tuple, ImmutableBytesWritable ptr) {
    AbstractBasePattern pattern = this.pattern;
    if (pattern == null) {
        // TODO: don't allow? this is going to be slooowwww
        if (!getPatternExpression().evaluate(tuple, ptr)) {
            if (logger.isTraceEnabled()) {
                logger.trace("LIKE is FALSE: pattern is null");
            }
            return false;
        }
        String value = (String) PVarchar.INSTANCE.toObject(ptr, getPatternExpression().getSortOrder());
        pattern = compilePattern(value);
        if (logger.isTraceEnabled()) {
            logger.trace("LIKE pattern is expression: " + pattern.pattern());
        }
    }
    Expression strExpression = getStrExpression();
    SortOrder strSortOrder = strExpression.getSortOrder();
    PVarchar strDataType = PVarchar.INSTANCE;
    if (!strExpression.evaluate(tuple, ptr)) {
        if (logger.isTraceEnabled()) {
            logger.trace("LIKE is FALSE: child expression is null");
        }
        return false;
    }
    String value = null;
    if (logger.isTraceEnabled()) {
        value = (String) strDataType.toObject(ptr, strSortOrder);
    }
    strDataType.coerceBytes(ptr, strDataType, strSortOrder, SortOrder.ASC);
    pattern.matches(ptr);
    if (logger.isTraceEnabled()) {
        boolean matched = ((Boolean) PBoolean.INSTANCE.toObject(ptr)).booleanValue();
        logger.trace("LIKE(value='" + value + "'pattern='" + pattern.pattern() + "' is " + matched);
    }
    return true;
}

Example 2 with PVarchar

use of org.apache.phoenix.schema.types.PVarchar in project phoenix by apache.

the class QueryCompilerTest method testColumnProjectionUnionAll.
