Troubleshooting SQLite Result Codes from Error 6 to 10


SQL return code 6 SQLITE_LOCKED
The SQLITE_LOCKED result code indicates that a write operation could not continue because of a conflict within the same database connection or a conflict with a different database connection that uses a shared cache.
For example, a DROP TABLE statement cannot be run while another thread is reading from that table on the same database connection because dropping the table would delete the table out from under the concurrent reader.

The SQLITE_LOCKED result code differs from SQLITE_BUSY in that SQLITE_LOCKED indicates a conflict on the same database connection (or on a connection with a shared cache) whereas SQLITE_BUSY indicates a conflict with a different database connection, probably in a different process.
SQL return code 7 SQLITE_NOMEM
The SQLITE_NOMEM result code indicates that SQLite was unable to allocate all the memory it needed to complete the operation. In other words, an internal call to sqlite3_malloc() or sqlite3_realloc() has failed in a case where the memory being allocated was required in order to continue the operation.

The SQLITE_READONLY result code is returned when an attempt is made to alter some data for which the current database connection does not have write permission.
The SQLITE_INTERRUPT result code indicates that an operation was interrupted by the sqlite3_interrupt() interface. See also: SQLITE_ABORT
SQL return code 10 SQLITE_IOERR
The SQLITE_IOERR result code says that the operation could not finish because the operating system reported an I/O error.
A full disk drive will normally give an SQLITE_FULL error rather than an SQLITE_IOERR error.
There are many different extended result codes for I/O errors that identify the specific I/O operation that failed.

Above are the list of SQLite Result Codes or Error Codes and their Description from Error 6 to 10 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.
