Troubleshooting SQLite Result Codes from Error 261 to 267


The SQLITE_BUSY_RECOVERY error code is an extended error code for SQLITE_BUSY that indicates that an operation could not continue because another process is busy recovering a WAL mode database file following a crash. The SQLITE_BUSY_RECOVERY error code only occurs on WAL mode databases.

The SQLITE_LOCKED_SHAREDCACHE error code is an extended error code for SQLITE_LOCKED indicating that the locking conflict has occurred due to contention with a different database connection that happens to hold a shared cache with the database connection to which the error was returned. For example, if the other database connection is holding an exclusive lock on the database, then the database connection that receives this error will be unable to read or write any part of the database file unless it has the read_uncommitted pragma enabled.
The SQLITE_LOCKED_SHARECACHE error code works very much like the SQLITE_BUSY error code except that SQLITE_LOCKED_SHARECACHE is for separate database connections that share a cache whereas SQLITE_BUSY is for the much more common case of separate database connections that do not share the same cache. Also, the sqlite3_busy_handler() and sqlite3_busy_timeout() interfaces do not help in resolving SQLITE_LOCKED_SHAREDCACHE conflicts.

The SQLITE_READONLY_RECOVERY error code is an extended error code for SQLITE_READONLY. The SQLITE_READONLY_RECOVERY error code indicates that a WAL mode database cannot be opened because the database file needs to be recovered and recovery requires write access but only read access is available.
SQL return code 266 SQLITE_IOERR_READ
The SQLITE_IOERR_READ error code is an extended error code for SQLITE_IOERR indicating an I/O error in the VFS layer while trying to read from a file on disk. This error might result from a hardware malfunction or because a filesystem came unmounted while the file was open.
The SQLITE_CORRUPT_VTAB error code is an extended error code for SQLITE_CORRUPT used by virtual tables. A virtual table might return SQLITE_CORRUPT_VTAB to indicate that content in the virtual table is corrupt.

Above are the list of SQLite Result Codes or Error Codes and their Description from Error 261 to 267 while performing certain operations against SQLite.

What are SQLite Errors?

SQLite programs have access to several types of common error information when the server returns an error. The SQLite message displayed contains three types of information:

A numeric error code. This number is SQLite and is not portable to other database systems. All result codes are integers. Symbolic names for all result codes are created using “#define” macros.Primary result code symbolic names are of the form “SQLITE_XXXXXX” where XXXXXX is a sequence of uppercase alphabetic characters. Extended result code names are of the form “SQLITE_XXXXXX_YYYYYYY” where the XXXXXX part is the corresponding primary result code and the YYYYYYY is an extension that further classifies the result code. The names and numeric values for existing result codes are fixed and unchanging. However, new result codes, and especially new extended result codes, might appear in future releases of SQLite.

Hope this was helpful.
