ADODB_mysql::ServerInfo (  ) 

Get server version info...

An array with 2 elements: $arr['string'] is the description string, and $arr[version] is the version (also a string).

Reimplemented from ADOConnection.

Definition at line 48 of file

References ADOConnection::_findvers(), and ADOConnection::GetOne().

& ADODB_mysql::MetaTables ( ttype = false,
showSchema = false,
mask = false 

ttype can either be 'VIEW' or 'TABLE' or false. If false, both views and tables are returned. "VIEW" returns only views "TABLE" returns only tables
showSchema returns the schema/user with the table name, eg. USER.TABLE
mask is the input mask - only supported by oci8 and postgresql
array of tables for current database.

Reimplemented from ADOConnection.

Definition at line 61 of file

References ADOConnection::MetaTables(), and qstr().

& ADODB_mysql::MetaIndexes ( table,
primary = FALSE,
owner = false 

List indexes on a table as an array.

table table name to query
primary true to only show primary keys. Not actually used for most databases
array of indexes on current table. Each element represents an index, and is itself an associative array.
Array ( [name_of_index] => Array ( [unique] => true or false [columns] => Array ( [0] => firstname [1] => lastname ) )

Reimplemented from ADOConnection.

Definition at line 79 of file

References ADOConnection::$false, ADOConnection::Execute(), and ADOConnection::SetFetchMode().

ADODB_mysql::qstr ( s,
magic_quotes = false 

Correctly quotes a string so that all strings are escaped. We prefix and append to the string single-quotes. An example is $db->qstr("Don't bother",magic_quotes_runtime());

s the string to quote
[magic_quotes] if $s is GET/POST var, set to get_magic_quotes_gpc(). This undoes the stupidity of magic quotes for GPC.
quoted string to be sent back to database

Reimplemented from ADOConnection.

Definition at line 133 of file

Referenced by MetaTables().

ADODB_mysql::GetOne ( sql,
inputarr = false 

Return first element of first row of sql statement. Recordset is disposed for you.

sql SQL statement
[inputarr] input bind array

Reimplemented from ADOConnection.

Definition at line 158 of file

References ADOConnection::GetOne(), and SelectLimit().

ADODB_mysql::BeginTrans (  ) 

Begin a Transaction. Must be followed by CommitTrans() or RollbackTrans().

true if succeeded or false if database does not support transactions

Reimplemented from ADOConnection.

Reimplemented in ADODB_mysqlt.

Definition at line 173 of file

References ADOConnection::outp().

ADODB_mysql::GenID ( seqname = 'adodbseq',
startID = 1 

Generates a sequence id and stores it in $this->genID; GenID is only available if $this->hasGenID = true;

seqname name of sequence to use
startID if sequence does not exist, start at this ID
0 if not supported, otherwise a sequence id

Reimplemented from ADOConnection.

Definition at line 201 of file

References ADOConnection::Execute().

& ADODB_mysql::MetaDatabases (  ) 

return the databases that the driver can connect to. Some databases will return an empty array.

an array of database names.

Reimplemented from ADOConnection.

Definition at line 226 of file

ADODB_mysql::SQLDate ( fmt,
col = false 

Reimplemented from ADOConnection.

Definition at line 242 of file

ADODB_mysql::Concat (  ) 

Different SQL databases used different methods to combine strings together. This function provides a wrapper.

param s variable number of string parameters

Usage: $db->Concat($str1,$str2);

concatenated string

Reimplemented from ADOConnection.

Definition at line 330 of file

ADODB_mysql::SelectDB ( dbName  ) 

Choose a database to connect to. Many databases do not support this.

dbName is the name of the database to select
true or false

Reimplemented from ADOConnection.

Definition at line 470 of file

Referenced by _connect(), _pconnect(), and MetaColumns().

& ADODB_mysql::SelectLimit ( sql,
nrows = -1,
offset = -1,
inputarr = false,
secs = 0 

Will select, getting rows from $offset (1-based), for $nrows. This simulates the MySQL "select * from table limit $offset,$nrows" , and the PostgreSQL "select * from table limit $nrows offset $offset". Note that MySQL and PostgreSQL parameter ordering is the opposite of the other. eg. SelectLimit('select * from table',3); will return rows 1 to 3 (1-based) SelectLimit('select * from table',3,2); will return rows 3 to 5 (1-based)

Uses SELECT TOP for Microsoft databases (when $this->hasTop is set) BUG: Currently SelectLimit fails with $sql with LIMIT or TOP clause already set

[offset] is the row to start calculations from (1-based)
[nrows] is the number of rows to get
[inputarr] array of bind variables
[secs2cache] is a private parameter only used by jlim
the recordset ($rs->databaseType == 'array')

Reimplemented from ADOConnection.

Definition at line 481 of file

ADODB_mysql::ErrorMsg (  ) 

the last error message

Reimplemented from ADOConnection.

Definition at line 504 of file

ADODB_mysql::ErrorNo (  ) 

the last error number. Normally 0 means no error.

Reimplemented from ADOConnection.
