Examples with GridSqlAst org.apache.ignite.internal.processors.query.h2.sql.GridSqlAst used on opensource projects

Example 1 with GridSqlAst

use of org.apache.ignite.internal.processors.query.h2.sql.GridSqlAst in project ignite by apache.

the class DmlAstUtils method findParams.

/**
 * @param qry Select.
 * @param params Parameters.
 * @param target Extracted parameters.
 * @param paramIdxs Parameter indexes.
 * @return Extracted parameters list.
 */

    if (params.length == 0)
        return target;
    for (GridSqlAst el : qry.columns(false)) findParams((GridSqlElement) el, params, target, paramIdxs);
    findParams((GridSqlElement) qry.from(), params, target, paramIdxs);
    findParams((GridSqlElement) qry.where(), params, target, paramIdxs);
    // Don't search in GROUP BY and HAVING since they expected to be in select list.
    findParams((GridSqlElement) qry.limit(), params, target, paramIdxs);
    findParams((GridSqlElement) qry.offset(), params, target, paramIdxs);

}

Example 2 with GridSqlAst

use of org.apache.ignite.internal.processors.query.h2.sql.GridSqlAst in project ignite by apache.
