[SQLConnect Params]...[/SQLConnect]

Generally speaking, the first step when using the SQL contexts is to make a connection to your database server. This is done with the [SQLconnect] context.

Example:

[SQLConnect dbType=MySQL&host=192.168.1.1&database=base&uid=sa&pwd=pass&conn_var=conn1]
<table>
<tr><td>Host:</td><td>[SQL_HOST]</td></tr>
<tr><td>Server Version:</td><td>[SQL_SERVERVER]</td></tr>
<tr><td>Client Version:</td><td>[SQL_CLIENTVER]</td></tr>
</table>
[/SQLConnect]


ParameterDescription
dbtype(Optional) - Can be one of three reserved values - MYSQL, MSSQL, or ORACLE - depending on the type of RDBMS you wish to connect to.If 'dbType' is not given, WebDNA defaults to MYSQL. For WebDNA 6.0, MYSQL is the only type supported.
host(Required) - Either the IP Address or the host name of the database server you wish to connect to.
port(Optional) - The non-standard/non-default port of the database host you wish to connect to; do not provide a value unless your database administrator has informed you that the you must use a specific port in order to connect to the server.
database(Optional) - The name of the database to which you wish to connect; almost all the time you will want to provide a database name to connect to; if you do not supply the "database" parameter, the engine assumes you wish to connect to the RDBMS as admin in order to execute admin-type tasks, such as creating tables, etc.; please note that in this case you will more than likely only be required to provide admin credentials in order to connect successfully.
uid(Optional) - The username credential you want to use to connect to the SQL server.
pwd(Optional unless uid is used) - The password credential you want to use to connect to the SQL server.
conn_var ( or just 'var')(Required) - the name of the connection variable that will be created on successful connection.


The following tags are available inside a [SQL] context:
