This information in the SQLCA and the SQLCODE field is updated after every API call for the SQL statement... SQLCA contains ERROR HANDLING data SQLCODE[edit] The SQLCODE field contains the SQL return code. The code can be zero (0), negative or positive. 0 means successful execution. Negative means unsuccessful with an error. An example

Common SQL Programming Mistakes 20 August 2009Ten Common SQL Programming MistakesIt is not always https://www.simple-talk.com/sql/t-sql-programming/ten-common-sql-programming-mistakes/ easy to spot "antipatterns" in your SQL, especially in more complex queries. In this article, Plamen demonstrates some of the most common SQL coding errors that he encounters, explains their root cause, and illustrates potential solutions. 418 57 Plamen Ratchev Database Lifecycle Management PatternsĀ & Practices Library Continuous Integration Programming in SQL can be both a error codes fun and a challenging task. Those with a background in traditional programming languages such as Java, C, C++, and VB often find it difficult to adapt to the "set-based" mindset. Even seasoned SQL developers and DBAs can get trapped in one of the many pitfalls of the SQL language. I have been there and I'm willing sql error codes to bet that you have too. Mastering the fundamentals takes time, and even then some mistakes are hard to spot. My intention with this article was to highlight some of the more common mistakes that I've seen people make when coding SQL. The list reflects my direct experience working with different development teams and developers, performing code review sessions, and so on, as well as the issues I see every day on the newsgroups and forums. The list of common mistakes is far from exhaustive, and is presented in no particular order of severity. In fact, the list could be regarded as the result of the following query: 123 SELECT TOP(10) mistakeFROM CommonSQLProgrammingMistakesORDER BY CHECKSUM(NEWID()); Without further ado, here is the list: NULLs and the NOT IN predicate Functions on indexed columns in predicates Incorrect subquery column Data type mismatch in predicates Predicate evaluation order Outer joins and placement of predicates Subqueries that return more than one value Use of SELECT * Scalar user-
