|This function is deprecated. This means that its use is discouraged and that it might not exist in future versions.|
Please use executeSQLQuery instead. See the examples at executeSQLQuery for equivalent UPDATE usage.
This function updates one or more rows in the database, by using the set parameter and conditions to change field values in specific rows.
The SQLite database contains globally stored data and can be used by scripts to store and retrieve data in a structured manner.
The executed SQL query is the following:
UPDATE <table> SET <set> WHERE <conditions>
bool executeSQLUpdate ( string tableName, string set, [ string conditions ] )
- tableName: The name of the table you want to modify.
- set: The query you want to execute on that table. The default SQL syntax is used, which means that the = is used to set a value and the ' is used to specify a value (e.g. test = 'hi' ). The , is used as a delimiter for multiple queries.
- conditions: The conditions that need to be met before a specific row is changed.
The function returns true on success, and false on failure.
This example creates a SQL table when a map loads, and stores info about a player to that database when he spawns.
function onMapLoad () -- create our table, if it doesn't already exist executeSQLCreateTable ( "players", "clothes_head_texture TEXT, clothes_head_model TEXT, player TEXT" ) end addEventHandler ( "onGamemodeMapStart", getRootElement(), onMapLoad ) function addInfoToSQL( theSpawnpoint, theTeam ) sourcename = getPlayerName ( source ) -- get the player's name -- try to retrieve the player data from the db result = executeSQLSelect ( "players", "player", "player = '" .. sourcename .. "'" ) if ( result == false ) then -- see if any data was found at all outputChatBox ( "This is your first time here! Welcome " .. sourcename .. "!", source ) executeSQLInsert ( "players", "'none', 'none', '" .. sourcename .. "'" ) else outputChatBox ( "Welcome back " .. sourcename .. "!", source ) executeSQLUpdate ( "players", "clothes_head_texture = 'hairgreen', clothes_head_model = 'somehead'", "player = '" .. sourcename .. "'" ) end -- get the clothes data for the player result = executeSQLSelect ( "players", "clothes_head_texture, clothes_head_model", "player = '" .. sourcename .. "'" ) outputChatBox ( "Your head texture is " .. result ) outputChatBox ( "Your head model is " .. result ) end addEventHandler ( "onPlayerSpawn", getRootElement(), addInfoToSQL )
