Member Function Documentation

begin()

DoliDB::begin

(

$textinlog = ''

)

Start transaction.

Parameters

string

$textinlog

Add a small text into log. '' by default.

Returns

int 1 if transaction successfully opened or already opened, 0 if error

Implements Database.

Reimplemented in TraceableDB.

commit()

DoliDB::commit

(

$log = ''

)

Validate a database transaction.

Parameters

string

$log

Add more log to default log line

Returns

int 1 if validation is OK or transaction level no started, 0 if ERROR

Implements Database.

getRow()

DoliDB::getRow

(

$sql

)

Return first result from query as object Note : This method executes a given SQL query and retrieves the first row of results as an object.

It should only be used with SELECT queries Don't add LIMIT to your query, it will be added by this method

Parameters

getRows()

DoliDB::getRows

(

$sql

)

Return all results from query as an array of objects.

Using this is a bad practice and is discouraged. Note : It should only be used with SELECT queries and with a limit. If you are not able to defined/know what can be the limit, it just means this function is not what you need. Do not use it.

Parameters

string

$sql

The sql query string. Must end with "... LIMIT x"
