Public ReadOnly Property ClientVersion As String
Property Value
The version of MySQL Client library (libmysql.dll or libmysqld.dll).
In the following example client and server versions are analysed, and, if both support
Devart.Common.DbCommand.Prepare() method, the process of preparing the query is initiated; otherwise the query is run unprepared.
public void GetMyData(string myConnectionString)
{
MySqlConnection myConn = new MySqlConnection(myConnectionString);
string mySelectQuery = "SELECT * FROM Test.Dept";
MySqlCommand myCommand = new MySqlCommand(mySelectQuery);
myCommand.Connection = myConn;
myConn.Open();
if (string.Compare(myConn.ClientVersion,"4.1")>=0
& string.Compare(myConn.ServerVersion,"4.1")>=0)
{
myCommand.Prepare();
}
try
{
MySqlDataReader myReader = myCommand.ExecuteReader();
...
myReader.Close();
}
finally
{
myConn.Close();
}
}

Dim Client_OK As Boolean = String.Compare(myConn.ClientVersion, "4.1") >= 0
Dim Server_OK As Boolean = String.Compare(myConn.ServerVersion, "4.1") >= 0

End Try
