SQL error messages are crucial for diagnosing issues in SQL queries and database operations. They provide information about what went wrong during query execution and allow users to troubleshoot and correct problems.

These error messages are often accompanied by error codes that give specific details about the type of error encountered.

SQL Error Messages

  • SQL error messages are feedback provided by a database management system (DBMS) when an issue occurs during the execution of SQL queries or commands.
  • These errors help developers understand what went wrong and why a query failed.
  • SQL error messages typically include an error code, a short description, and sometimes a detailed explanation.

Error Codes 0 and 100

These error codes indicate standard outcomes for SQL operations. SQLCODE 0 denotes a successful execution, while SQLCODE 100 indicates that a query was executed without errors but did not return any rows.

Error CodeDescription
0Successful execution of the SQL statement. No errors occurred.
100No data found; used by some SQL databases to indicate that a query has returned no rows.

Error Codes -1 to -99

This range of error codes includes various general SQL issues, such as syntax errors, data type mismatches and permission problems. Understanding these errors can help diagnose common SQL issues.

Error CodeDescription
-1General SQL error; the specific issue is not defined.
-2Invalid SQL statement or syntax error in the SQL query.
-3Out of memory; the system could not allocate the required memory.
-4Database connection error; unable to establish or maintain a connection.
-5Data type mismatch; trying to insert or process incompatible data types.
-6Numeric overflow; value exceeds the storage capacity.
-7Permission denied; user lacks necessary privileges for the operation.
-8Constraint violation; such as a unique constraint or foreign key constraint failure.
-9Invalid operation; performing an operation that is not allowed.
-10Deadlock; two or more transactions are waiting for each other to release locks.
-11Timeout; the operation took longer than the permitted time limit.
-12Data integrity issue; corruption or mismatch in data.

-14Unspecified SQL error; general error with no specific cause.
-15Authentication error; issues with user credentials or login.
-16Database not found; the specified database does not exist.
-17Query execution error; issues encountered during SQL query execution.

Error Codes -101 to -399

This range includes more specific SQL error messages related to feature support, query execution, and data integrity. They can provide insights into advanced SQL issues and database feature limitations.
