示例1: executeQuery
import org.apache.kylin.query.relnode.OLAPContext; //導入方法依賴的package包/類
protected SQLResponse executeQuery(String sql, SQLRequest sqlRequest) throws Exception {
sql = sql.trim().replace(";", "");
int limit = sqlRequest.getLimit();
if (limit > 0 && !sql.toLowerCase().contains("limit")) {
sql += (" LIMIT " + limit);
}
int offset = sqlRequest.getOffset();
if (offset > 0 && !sql.toLowerCase().contains("offset")) {
sql += (" OFFSET " + offset);
}
// add extra parameters into olap context, like acceptPartial

parameters.put(OLAPContext.PRM_ACCEPT_PARTIAL_RESULT, String.valueOf(sqlRequest.isAcceptPartial()));
OLAPContext.setParameters(parameters);
return execute(sql, sqlRequest);
}
示例2: setUser
