Hello there, I'm curious about something related to SQL queries. I understand how to execute one query at a time, but I'm wondering how I can run two SQL queries simultaneously or sequentially within the same process. Is there a specific syntax or approach I should be following to achieve this? Perhaps you could guide me through the steps or provide an example to illustrate the process. Thanks in advance for your assistance.

Subsequent to properly structuring your multi-statement query, it is necessary to adjust the global variable DSQEC_RUN_MQ to a value of 1. This manipulation authorizes the system to recognize and process all statements within the query, rather than merely executing the first and neglecting the rest.

By setting DSQEC_RUN_MQ to 1, you empower the database to embark on a comprehensive execution of your multi-statement query. Each segment, properly delimited by semicolons, will be methodically addressed and fulfilled in the order presented.

Conversely, if DSQEC_RUN_MQ is left at its default value of 0 or is explicitly set to that number, the database will exhibit a more restrictive behavior. Specifically, it will solely execute the initial statement encountered within the query, disregarding any subsequent instructions that follow semicolons.

This feature serves as a safety mechanism, enabling users to preview the effects of their primary statement without inadvertently altering the database state with unintended consequences from additional, unreviewed commands.

When executing a query that encompasses multiple statements, it is imperative to meticulously separate each individual statement with a semicolon. This delineation ensures that the database system can accurately distinguish between distinct commands, thereby preventing any potential confusion or errors.
