Use the following commands to start a specific SQL interpreter:
-psql by PostGres: \\[sql-postgres]
-mysql by TcX: \\[sql-mysql]
-SQL*Plus by Oracle: \\[sql-oracle]
-dbaccess by Informix: \\[sql-informix]
-isql by Sybase: \\[sql-sybase]
-sql by Ingres: \\[sql-ingres]
-isql by Microsoft: \\[sql-ms]
+ psql (PostGres): \\[sql-postgres]
+
+Other non-free SQL implementations are also supported:
+
+ mysql: \\[sql-mysql]
+ SQL*Plus: \\[sql-oracle]
+ dbaccess Informix: \\[sql-informix]
+ Sybase: \\[sql-sybase]
+ Ingres: \\[sql-ingres]
+ Microsoft: \\[sql-ms]
+
+But we urge you to choose a free implementation instead of these.
Once you have the SQLi buffer, you can enter SQL statements in the
buffer. The output generated is appended to the buffer and a new prompt
(defun sql-mysql ()
"Run mysql by TcX as an inferior process.
+Note that the widespread idea that mysql is free software
+is inaccurate; its license is too restrictive.
+We urge you to use PostGres instead.
-If buffer *SQL* exists but no process is running, make a new process.
+If buffer `*SQL*' exists but no process is running, make a new process.
If buffer exists and a process is running, just switch to buffer
`*SQL*'.
