Example 1 with DbQuery

use of com.axway.ats.common.dbaccess.DbQuery in project ats-framework by Axway.

the class DatabaseOperations method getDatabaseDataAsStrings.

/**
     * <p>
     * Gets data from a database table. All values as returned as String representations as needed.<br>
     * For example:
     * <ul>
     *  <li>TIMESTAMPs are retuned as java.sql.Timestamp.toString() format
     *  (yyyy-MM-dd HH:mm:ss.SSS and millis instead of nanos as documented in JavaSE Doc)</li>
     *  <li>BLOBs bytes are represented in hex format. Beware not to select too big data cells.</li>
     * </ul>
     * </p>
     * @param sqlQuery the SQL SELECT query to run. Client is resposible for any
     *      possible escaping needed so thread this as not security-safe method
     * @return the found database data
