Several DBMS have already been tested, but more will be added later. Load JDBC driver Connect to any JDBC compatible database. Discover DbSchema layouts, virtual foreign keys, Relational Data Browse, interactive PDF documentation and many other features.Import database schemas Build meaningful relations between tables and document the schema. Db Schema is build for large schemas and complex databases. And even so, I'd still be looking to use CREATE EXTERNAL TABLE and MERGE.DbSchema 8.2.5 Download for Windows 10, 8, 7ĭbSchema is a diagram-oriented database Windows PC software compatible with all relational and many No-SQL databases, like MySql, Cassandra, PostgreSql, MongoDb schema visualization, Redshift, SqlServer, Azure, Oracle, Teradata and more. Using plain ESQL/C is another option, but only for masochists like myself (who've been using it for æons). I4GL does not use JDBC at all it is built atop Informix ESQL/C. I'm sure it is confusing for you, too you're not terribly familiar with Informix and you're not quite sure what you've got and what you're using. Or you could use CREATE EXTERNAL TABLE and MERGE in SQL. If you are using I4GL, you can create your temporary table and then (probably) load the data into it, and then do your matching work. I've no idea how DB Visualizer would fit into that system. Are you using Informix 4GL (I4GL) or some other language? I4GL is a separate product that must be purchased, and creates compiled programs that run against the database. You can do it in another way if you wish - be my guest. The MERGE statement automatically (with no programming on your part) does things like 'update the first name because it is different'. The CREATE EXTERNAL TABLE statement allows IDS to treat the file as if it was a table. Given the extra information now in the question, I am more convinced than ever that using CREATE EXTERNAL TABLE that specifies the file you've got on disk as the data source and the MERGE statement is exactly what you need. You could place the COMMIT after the DROP you could need another COMMIT after the DROP if you have a MODE ANSI database. ![]() On the whole though, your database should be logged. The BEGIN and COMMIT aren't necessary if you have a non-logged database (but why?). Check the syntax I'm inventing on the fly! In theory, that's about 5 SQL commands: BEGIN WORK ĬREATE EXTERNAL TABLE mergeable_data (.). Assuming you are using a recent enough version of Informix (12.10, or 11.70), then you should probably be looking to map the file to an external table, and then using the MERGE command to merge the updates and inserts (and possibly deletes) from the external table into the new table.
