[Library] MySQL Prepared Statements

[PatrickGTR]

Introduction

Hi, I'll keep it short and simple.?

This emulates prepared statement when using the MySQL plugin.

Thank you for reading this really long introduction.

Important: sampctl required! check github repository for installation instructions.



Reading Data (using inline)

Code:

new stmt_readloop = MySQL_PrepareStatement(MySQLHandle, "SELECT * FROM spawns");



// Run Threaded on statement

inline OnSpawnsLoad() {

? ? new

? ? spawnID,

? ? Float:spawnX,

? ? Float:spawnY,

? ? Float:spawnZ,

? ? Float:spawnA;



? ? MySQL_BindResultInt(stmt_readloop, 0, spawnID);

? ? MySQL_BindResultFloat(stmt_readloop, 1, spawnX);

? ? MySQL_BindResultFloat(stmt_readloop, 2, spawnY);

? ? MySQL_BindResultFloat(stmt_readloop, 3, spawnZ);

? ? MySQL_BindResultFloat(stmt_readloop, 4, spawnA);



? ? while(MySQL_Statement_FetchRow(stmt_readloop)) {

? ? ? ? printf("%i, %.3f, %.3f, %.3f", spawnID, spawnX, spawnY, spawnZ, spawnA);

? ? }

? ? MySQL_StatementClose(stmt_readloop);

}

MySQL_ExecuteThreaded_Inline(stmt_readloop, using inline OnSpawnsLoad);

Writing Data

Code:

new Statement: stmt_insert = MySQL_PrepareStatement(MySQLHandle, "INSERT INTO accounts(username, password, salt, money, kills, deaths) VALUES (?,?,?,?,?,?) " );



// Arrow values in questions (first 0, second is 1, etc ...)

MySQL_Bind(stmt_insert, 0 , "patrickgtr");

MySQL_Bind(stmt_insert, 1 , "patrickgtrpassword");

MySQL_Bind(stmt_insert, 2 , "pgtrhash");

MySQL_BindInt(stmt_insert, 3, 100);

MySQL_BindInt(stmt_insert, 4, 200);

MySQL_BindInt(stmt_insert, 5, 300);



MySQL_ExecuteParallel(stmt_insert);

MySQL_StatementClose(stmt_insert);

Functions



Open/Close

Code:

MySQL_StatementClose(Statement:statement)

MySQL_PrepareStatement(MySQL:handle, const query[])

MySQL_Statement_RowsLeft(&Statement:statement)

MySQL_Statement_FetchRow(Statement:statement)

Writing

Code:

MySQL_Bind(Statement:statement, param, const str[])?

MySQL_BindInt(Statement:statement, param, value)

MySQL_BindFloat(Statement:statement, param, Float:value)

Reading

Code:

MySQL_BindResult(Statement:statement, field, const result[], len = sizeof(result))

MySQL_BindResultInt(Statement:statement, field, &result)

MySQL_BindResultFloat(Statement:statement, field, &Float:result)

Executing

Code:

MySQL_ExecuteThreaded(Statement:statement, const callback[] = "", const fmat[] = "", {Float,_}:...)

MySQL_ExecuteParallel(Statement:statement, const callback[] = "", const fmat[] = "", {Float,_}:...)

MySQL_ExecuteThreaded_Inline(Statement:statement, Func:callback<>)

MySQL_ExecuteParallel_Inline(Statement:statement, Func:callback<>)

Love it - will switch to this.

Love it - will switch to this.

Ah thank you, glad you find it useful.

[XoMoX]

Yes to avoid SQL injections very very nice

[PatrickGTR]

Code updated!



- Fix the issue where a data would get loaded DESC instead of ASC.

- stmt_fetch_row is not depending on loop to retrieve next row.

- fix typo in Debug of stmt_fetch_row.

- format code a lil bit more (like it matters much lol)

[PatrickGTR]

added bcrypt example to Prepared Statement as requested.
