Most other result codes indicate an error. + + +<!---------------------------------------------------------------> +<a name="error"></a> +<h3>(1) SQLITE_ERROR</h3> +<p> + The SQLITE_ERROR result code is a generic error code that is used when + no other more specific error code is available. + + +<!---------------------------------------------------------------> +<a name="internal"></a> +<h3>(2) SQLITE_INTERNAL</h3> +<p> + The SQLITE_INTERNAL result code indicates an internal malfunction. + In a working version of SQLite, an application should never see this + result code. If application does encounter this result code, it shows + that there is a bug in the database engine. + <p> + SQLite does not currently generate this result code. + However, <a href="appfunc.html">application-defined SQL functions</a> or + <a href="vtab.html">virtual tables</a>, or <a href="vfs.html">VFSes</a>, or other extensions might cause this + result code to be returned. + + +<!---------------------------------------------------------------> +<a name="perm"></a> +<h3>(3) SQLITE_PERM</h3> +<p> + The SQLITE_PERM result code indicates that the requested access mode + for a newly created database could not be provided. + + +<!---------------------------------------------------------------> +<a name="abort"></a> +<h3>(4) SQLITE_ABORT</h3> +<p> + The SQLITE_ABORT result code indicates that an operation was aborted + prior to completion, usually be application request. + See also: <a href="rescode.html#interrupt">SQLITE_INTERRUPT</a>. + <p> + If the callback function to <a href="c3ref/exec.html">sqlite3_exec()</a> returns non-zero, then + sqlite3_exec() will return SQLITE_ABORT. + <p> + If a <a href="lang_transaction.html">ROLLBACK</a> operation occurs on the same <a href="c3ref/sqlite3.html">database connection</a> as + a pending read or write, then the pending read or write may fail with + an SQLITE_ABORT or <a href="rescode.html#abort_rollback">SQLITE_ABORT_ROLLBACK</a> error. + <p> + In addition to being a result code, + the SQLITE_ABORT value is also used as a <a href="c3ref/c_fail.html">conflict resolution mode</a> + returned from the <a href="c3ref/vtab_on_conflict.html">sqlite3_vtab_on_conflict()</a> interface. + + +<!---------------------------------------------------------------> +<a name="busy"></a> +<h3>(5) SQLITE_BUSY</h3> +<p> + The SQLITE_BUSY result code indicates that the database file could not + be written (or in some cases read) because of concurrent activity by + some other <a href="c3ref/sqlite3.html">database connection</a>, usually a database connection in a + separate process. + <p> + For example, if process A is in the middle of a large write transaction + and at the same time process B attempts to start a new write transaction, + process B will get back an SQLITE_BUSY result because SQLite only supports + one writer at a time.
