Opening MySQL Databases

There are several ways to connect to MySQL databases in Database Tour:

1. Opening through FD interface (currently, supported are MySQL versions from 3.21 up to 5.7). Select FD interface, click MySQL, then fill all needed database parameters. Consult with your database administrator on how to choose correct parameters.

   MySQL database connection parameters:

   (required parameters are highlighted)

   Parameter	Description	Value example
   Vendor library	MySQL client library	C:\Program Files\MySQL\MySQL Server 5.7\lib\libmysql.dll
   Server	IP address or hostname of the server	localhost
   Port	The server's listening port	3306
   Database	Name of the current database for the connection	mysql
   Compress	Specify whether to enable network traffic compression	False
   Charset	Default character set for the connection	UTF8
   User name	Database user name	root
   Password	Database user password	********
   SQL command separator	Command separator in multi-command SQL scripts	;

2. Opening through connection string. Select ADO interface, then choose Connection string option and write a connection string. This way is very flexible and allows to specify many additional parameters in the connection string and override standard Database Tour connection behavior. It is recommended for advanced users. Here are basic connection strings (more examples and details can be found in the Internet):

   Provider=MySQLProv;Data Source=mydb;User Id=myUsername;Password=myPassword;   (MySQL OLEDB Provider must be installed)

   Extended Properties="DSN=MySQLDSN;UID=root;PWD=root;"

3. Opening through ODBC DSN. Create (if it does not exist yet) an ODBC DSN of the corresponding type using Windows ODBC Data Source Administrator, and point it to the database. Then:

   - Select FD interface, click ODBC, then point the Data source parameter to the ODBC DSN by selecting it from the drop-down list.

   or

   - Select ADO or BDE interface, then choose ODBC data source option and then select the needed ODBC DSN from the drop-down list.

Notes

1. MySQL client must be installed. The bit-version of it (32 or 64) must match the bit-version of the application.
2. When choosing the ODBC option, please make sure the corresponding ODBC driver installed and the bit-version of it matches the bit-version of the application (32 or 64).

Hints

• Each Database Tour edition has both 32-bit and 64-bit versions. You can install both and use them depending on what type of database you need to work with.
• You can invoke the ODBC Data Source Administrator directly from Database Tour when it was launched in administrator mode. In Connect / Open Data Source window, switch to ADO, then click ODBC Sources... button.
