Example 5 with ValueReadQuery

use of org.eclipse.persistence.queries.ValueReadQuery in project eclipselink by eclipse-ee4j.

the class HSQLPlatform method getTimestampQuery.

@Override
public ValueReadQuery getTimestampQuery() {
    if (this.timestampQuery == null) {
        this.timestampQuery = new ValueReadQuery();
        this.timestampQuery.setSQLString("CALL CURRENT_TIMESTAMP");
        this.timestampQuery.setAllowNativeSQLQuery(true);
    }
    return this.timestampQuery;
