Sqlite database error attempt to write a readonly database schema

Result Code Meanings Overview Many of the routines in the SQLite C-language Interface return numeric result codes indicating either success or failure, and in the event of a failure, providing some idea of the cause of the failure. This document strives to explain what each of those numeric result codes means. Result Codes versus Error Codes "Error codes" are a subset of "result codes" that indicate that something has gone wrong.

SQLite Result Codes

Result Code Meanings Overview Many of the routines in the SQLite C-language Interface return numeric result codes indicating either success or failure, and in the event of a failure, providing some idea of the cause of the failure.

This document strives to explain what each of those numeric result codes means. Result Codes versus Error Codes "Error codes" are a subset of "result codes" that indicate that something has gone wrong.

There are only a few non-error result codes: The term "error code" means any result code other than these three.

The least significant 8 bits of the result code define a broad category and are called the "primary result code". More significant bits provide more detailed information about the error and are called the "extended result code" Note that the primary result code is always a part of the extended result code.

Given a full bit extended result code, the application can always find the corresponding primary result code merely by extracting the least significant 8 bits of the extended result code.

SQLite C Interface

All extended result codes are also error codes. Hence the terms "extended result code" and "extended error code" are interchangeable.

For historic compatibility, the C-language interfaces return primary result codes by default. Definitions All result codes are integers. Symbolic names for all result codes are created using " define" macros in the sqlite3. There are separate sections in the sqlite3. 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. Most other result codes indicate an error. 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. SQLite does not currently generate this result code. However, application-defined SQL functions or virtual tablesor VFSesor other extensions might cause this result code to be returned.

Process B will need to wait for process A to finish its transaction before starting a new transaction. 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.

Note that this error can occur when trying to write information into the main database file, or it can also occur when writing into temporary disk files.

Sometimes applications encounter this error even though there is an abundance of primary disk space because the error occurs when writing into temporary disk files on a system where temporary files are stored on a separate partition with much less space that the primary disk. The file in question might be a primary database file or on of several temporary disk files.

There is a race condition that can occur when two separate database connections both try to start a transaction at the same time in WAL mode.

The loser of the race backs off and tries again, after a brief delay. If the database schema was changed by some other process in between the time that the statement was prepared and the time the statement was run, this error can result.

The maximum length of an SQL statement defaults to a much smaller value of 1, bytes.

SQLite is normally very forgiving about mismatches between the type of a value and the declared type of the container in which that value is to be stored. But in a few cases, SQLite is strict about types. The rowid of a table must be an integer.

SQLite tries to detect misuse and report the misuse using this result code. However, there is no guarantee that the detection of misuse will be successful. Misuse detection is probabilistic. The default behavior is for that extension to be automatically unloaded when the database connection closes.

This error might result from a hardware malfunction or because a filesystem came unmounted while the file was open. This can serve as a warning to application designers that the database might benefit from additional indexes. Pending write operations always fail with this error when a rollback occurs.

Process A keeps the transaction open.Join Stack Overflow to learn, share knowledge, and build your career. means that the database engine attempted to open a locked database and there is no busy callback registered (so, it can’t perform the action). SQLITE_ERROR (1) means that a run-time error, such as a constraint violation, has occurred.

- full information and how to uninstall it, and how to keep your system tray clean. MUSHclient supports any number of SQLite databases open simultaneously. To distinguish between them, you supply a "database id" which is just a string you choose to identify each one.

Nov 01,  · In this case just drop the sqlite database and create it new with the given zabbix schema. basically just follow the zabbix proxy installation guide on how to create the database. The SQLITE_BUSY result code differs from SQLITE_LOCKED in that SQLITE_BUSY indicates a conflict with a separate database connection, probably in a separate process, whereas SQLITE_LOCKED indicates a conflict within the same database connection (or sometimes a database connection with a shared cache).
