Databases Supported

The name below is the value you pass to NewADOConnection($name) to create a connection object for that database.

Name Tested Database RecordCount() usable Prerequisites Operating Systems
access B Microsoft Access/Jet. You need to create an ODBC DSN. Y/N ODBC Windows only
ado B

Generic ADO, not tuned for specific databases. Allows DSN-less connections. For best performance, use an OLEDB provider. This is the base class for all ado drivers.

You can set $db->codePage before connecting.

? depends on database ADO or OLEDB provider Windows only
ado_access B Microsoft Access/Jet using ADO. Allows DSN-less connections. For best performance, use an OLEDB provider. Y/N ADO or OLEDB provider Windows only
ado_mssql B Microsoft SQL Server using ADO. Allows DSN-less connections. For best performance, use an OLEDB provider. Y/N ADO or OLEDB provider Windows only
db2 C Uses PHP's db2-specific extension for better performance. Y/N DB2 CLI/ODBC interface

Unix and Windows. Requires IBM DB2 Universal Database client.

odbc_db2 C Connects to DB2 using generic ODBC extension. Y/N DB2 CLI/ODBC interface

Unix and Windows. Unix install hints. I have had reports that the $host and $database params have to be reversed in Connect() when using the CLI interface.

vfp A Microsoft Visual FoxPro. You need to create an ODBC DSN. Y/N ODBC Windows only
fbsql C FrontBase. Y ?

Unix and Windows

ibase B Interbase 6 or earlier. Some users report you might need to use this
$db->PConnect('localhost:c:/ibase/employee.gdb', "sysdba", "masterkey") to connect. Lacks Affected_Rows currently.

You can set $db->role, $db->dialect, $db->buffers and $db->charSet before connecting.
Y/N Interbase client Unix and Windows
firebird B Firebird version of interbase. Y/N Interbase client Unix and Windows
borland_ibase C Borland version of Interbase 6.5 or later. Very sad that the forks differ. Y/N Interbase client Unix and Windows
informix C Generic informix driver. Use this if you are using Informix 7.3 or later. Y/N Informix client Unix and Windows
informix72 C Informix databases before Informix 7.3 that do no support SELECT FIRST. Y/N Informix client Unix and Windows
ldap C LDAP driver. See this example for usage information.   LDAP extension ?
mssql A

Microsoft SQL Server 7 and later. Works with Microsoft SQL Server 2000 also. Note that date formating is problematic with this driver. For example, the PHP mssql extension does not return the seconds for datetime!

Y/N Mssql client

Unix and Windows.
Unix install howto and another one.

mssqlpo A

Portable mssql driver. Identical to above mssql driver, except that '||', the concatenation operator, is converted to '+'. Useful for porting scripts from most other sql variants that use ||.

Y/N Mssql client

Unix and Windows.
Unix install howto
.

mysql A MySQL without transaction support. You can also set $db->clientFlags before connecting. Y MySQL client Unix and Windows
mysqli B Supports the newer PHP5 mysql api. Y MySQL 4.1+ client Unix and Windows
mysqlt or maxsql A

MySQL with transaction support. We recommend using || as the concat operator for best portability. This can be done by running MySQL using:
mysqld --ansi or mysqld --sql-mode=PIPES_AS_CONCAT

Y/N MySQL client Unix and Windows
oci8 A Oracle 8/9. Has more functionality than oracle driver (eg. Affected_Rows). You might have to putenv('ORACLE_HOME=...') before Connect/PConnect.

There are 2 ways of connecting - with server IP and service name:
PConnect('serverip:1521','scott','tiger','service')
or using an entry in TNSNAMES.ORA or ONAMES or HOSTNAMES:
PConnect(false, 'scott', 'tiger', $oraname).

Since 2.31, we support Oracle REF cursor variables directly (see ExecuteCursor).

Y/N Oracle client Unix and Windows
oci805 C Supports reduced Oracle functionality for Oracle 8.0.5. SelectLimit is not as efficient as in the oci8 or oci8po drivers. Y/N Oracle client Unix and Windows
oci8po A Oracle 8/9 portable driver. This is nearly identical with the oci8 driver except (a) bind variables in Prepare() use the ? convention, instead of :bindvar, (b) field names use the more common PHP convention of lowercase names.

Use this driver if porting from other databases is important. Otherwise the oci8 driver offers better performance.

Y/N Oracle client Unix and Windows
odbc A Generic ODBC, not tuned for specific databases. To connect, use
PConnect('DSN','user','pwd'). This is the base class for all odbc derived drivers.
? depends on database ODBC Unix and Windows. Unix hints.
odbc_mssql A Uses ODBC to connect to MSSQL Y/N ODBC Unix and Windows.
odbc_oracle C Uses ODBC to connect to Oracle Y/N ODBC Unix and Windows.
odbtp B Generic odbtp driver. Odbtp is a software for accessing Windows ODBC data sources from other operating systems. Y/N odbtp Unix and Windows
odbtp_unicode C Odtbp with unicode support Y/N odbtp Unix and Windows
oracle C Implements old Oracle 7 client API. Use oci8 driver if possible for better performance. Y/N Oracle client Unix and Windows
netezza C Netezza driver. Netezza is based on postgres code-base. Y ? ?
pdo C Generic PDO driver for PHP5. Y PDO extension and database specific drivers Unix and Windows.
postgres A Generic PostgreSQL driver. Currently identical to postgres7 driver. Y PostgreSQL client Unix and Windows.
postgres64 A For PostgreSQL 6.4 and earlier which does not support LIMIT internally. Y PostgreSQL client Unix and Windows.
postgres7 A PostgreSQL which supports LIMIT and other version 7 functionality. Y PostgreSQL client Unix and Windows.
postgres8 A Version supporting Postgresql 8 features Y PostgreSQL client Unix and Windows.
postgres9 A Version supporting Postgresql 9 features Y PostgreSQL client Unix and Windows.
sapdb C SAP DB. Should work reliably as based on ODBC driver. Y/N SAP ODBC client

?

sqlanywhere C Sybase SQL Anywhere. Should work reliably as based on ODBC driver. Y/N SQL Anywhere ODBC client

?

sqlite B SQLite. Y -

Unix and Windows.

sqlitepo B Portable SQLite driver. This is because assoc mode does not work like other drivers in sqlite. Namely, when selecting (joining) multiple tables, the table names are included in the assoc keys in the "sqlite" driver.

In "sqlitepo" driver, the table names are stripped from the returned column names. When this results in a conflict, the first field get preference.

Y -

Unix and Windows.

sybase C Sybase. Y/N Sybase client

Unix and Windows.


The "Tested" column indicates how extensively the code has been tested and used.
A = well tested and used by many people
B = tested and usable, but some features might not be implemented
C = user contributed or experimental driver. Might not fully support all of the latest features of ADOdb.

The column "RecordCount() usable" indicates whether RecordCount() return the number of rows, or returns -1 when a SELECT statement is executed. If this column displays Y/N then the RecordCount() is emulated when the global variable $ADODB_COUNTRECS=true, which is the default. Note that for large recordsets, it might be better to disable RecordCount() emulation because substantial amounts of memory are required to cache the recordset for counting. This variable is checked every time a query is executed, so you can selectively choose which recordsets to count.
