I have a connection string in my config files like so
add name="entities" connectionString="Data Source=localhost;user id=username;password=somepassword;persist security info=True;database=dbname" providerName="MySql.Data.MySqlClient"
This works with localhost.
As soon as I change the Data Source to Data Source=123.34.45.56 <-- some remote server
I get MySql.Data.MySqlClient.MySqlException: Table 'mydb.Emails'
doesn't exist
If I use connection code in c# it will work against the remote server : Example below
MySql.Data.MySqlClient.MySqlConnection mySqlConnection = new
MySql.Data.MySqlClient.MySqlConnection();
mySqlConnection.ConnectionString = "Data Source=123.34.45.56;user id=username;password=somepassword;persist security info=True;database=dbname";
string conString = mySqlConnection.ConnectionString;
using (MySqlConnection connection = new MySqlConnection(conString)) {
connection.Open();
using (MySqlCommand command = new MySqlCommand(
"SELECT * FROM emails",
connection)) {
using (MySqlDataReader reader = command.ExecuteReader()) {
while (reader.Read()) {
for (int i = 0; i < reader.FieldCount; i++) {
var tr = reader.GetValue(i);
}
}
}
}
}
How come the connection string in the web.config is throwing this error for every table MySql.Data.MySqlClient.MySqlException: Table 'mydb.Emails'
doesn't exist.
The tables are there as the c# connection code can open a connection and query the data just fine.
How do I get the connection string to work?
John Garrard was correct. It was a case sensitivity issue with the database located on two different operating systems. I needed to make my entities case sensitive and the switching the connection string will work between the Windows development machine and the Linux production machine. Thanks.
I came across this issue when moving from a Windows dev to AWS test system. There is a parameter called "lower_case_table_names" that controls how MySql matches table names which defaults to 0 on linux and 1 in Windows (meaning case sensitive and insensitive):
