#UNLOCK SQLITE DATABASE HOW TO#

How to solve General error 5 database is locked manually? While attempting to do two Select operations in a multithreaded program simultaneously on a table. Because SQLite is a lightweight database, a higher level of competition can not be managed.The error message indicates that a similar operation can not be performed by using the same database connection or a different link to the database using a shared cache, as there is a transaction event.While attempting to create or drop a list, a Select Thread appears on the table.An NFS locking problem generates SQLite locked error.

#UNLOCK SQLITE DATABASE CODE#

Normally, this error code occurs when an SQLite user attempts to perform two unauthorized transactions or operations on the same data connection and the same other server details.

РІР‚СљSQLite Error Database is lockedРІР‚Сњ Factors In this blog, weРІР‚в„ўre focusing on this error and providing you with the best way to get out of that state.Р”Р‡irst of all, you should know all the factors that are responsible for generating this error. This also causes the database to get lock. $result = $bulkload_connection -> exec ( 'insert into bulkload.When performing transactions with SQLite Database, there is a situation where the user encounters an РІР‚СљSQLite error Database is locked code 5РІР‚Сњ problem. copy the rows from the source table to the target table as quickly as possible $result = $bulkload_connection -> exec ( $targettbl_create_statement )

issue the query to create the target table within the target database file If ( $result = false ) exit( $bulkload_connection -> lastErrorMsg ()) $result = $bulkload_connection -> exec ( 'attach 'c:/sqlite3_database_files/target.db' as bulkload' )

attach the target database file to the bulkload connection object - and reference it as the database called $targettbl_create_statement = str_replace ( 'CREATE TABLE my_template', 'CREATE TABLE bulkload.working_table', $sourcetbl_create_statement ) build the create statement query for the target table If ( $sourcetbl_create_statement = false ) exit( $bulkload_connection -> lastErrorMsg ()) querySingle ( 'select sql from sqlite_master where type='table' and name='my_template'' ) You want to make a copy of this table into the database file 'target.db' and call the table 'working_table'. * SQLite3 has an 'attach as ' which will allow multiple database files to be opened and accessible to the same SQLite3 object.Р”Р„ssume you have a table called 'my_template' in the SQLite3 database file 'source.db'. * SQLite3 supports the 'insert lect * from' SQL syntax for doing bulkload-speed inserts into a table - but what if the source and target tables are in separate database files? * The create statement query for a table is stored within a table called 'sqlite_master' within the parent database file. These are the nice features within SQLite3 that are leveraged: This took some investigation on my part, so hopefully the solution I found will help you too. If you are trying to use the open() method to open multiple database files within the same SQLite3 object (which I could not get to work), here is an alternative way to do so using special SQLite3 syntax additions to the SQL language.
