I have two .sql file for MySql database with same tables but different rows.
How can I make one .sql file with the datas of other two?
If your files contain data only (DML - SELECTs, INSERTs etc.), then you can join them simply via notepad. But both of files must contain the same table (the same columns)!

I have multiple excel files that I need to merge and upload in one database. However, I cannot Distribute the fields into its corresponding tables in the database. I can only send it to one table at a time. Is there any other way to do this? How can I have multiple target table?
P.S. I'm using MySQL Workbench for the database.
Thank you for your help!
You can connect multiple Table output steps to your last processing step and set it to copy all rows to both or all target steps. Connect Table outputs (or Insert/update, etc) like in the image, then right-click the step where the stream splits and select Copy Data to Next Steps. In the Table outputs you obviously only specify the columns that apply to that table.
I have 3 data files and 3 tables. Is there any way to enter the data from the data files to their respective tables using only a single control file using parameters.
I know that we can use multiple datafiles to insert data into single table but i want multiple datafiles to insert data into multiple tables.
I have not done it, but you can specify multiple files as long as they are the same layout by using multiple INFILE clauses. Then as long as there is some identifier in the record, you can use multiple INTO TABLE clauses, each with its own WITH clause. See the control file reference for more info. Please let us know how it works out.
I have 2 separate sql databases, they both have the same field but are not attached and are completely separate files. One of the database files has a few hundred rows of data and I want to copy a few of those rows into the other database file. Some people have said to use sql statements to copy the data but the databases are not linked in any way so I am not sure as to how these statements would work. Is there no software where I can just select the correct rows and copy them over, or create a new database with the ones selected?
I hope this makes sense, thanks.
Regardless of the database platform you are using, there should be commands/tools that will allow you to perform bulk data imports and exports from/to a file (e.g. a CSV file). Try exporting the rows you wish to copy from the database on the first server into an intermediate file, copying that file to the second server, and then importing it into that database.
I have a MySQL Server which has one database called "Backup".
It only has one table with the name "storage".
In the Backup db the storage table contains about 5 Millions datarows.
Now I wanted to append new rows to the table by using the "source" command in the SQL command line.
So what happend is, that source uploaded all the new files in the table, but it overwrote the existing entries (seems that he first deleted all data)
What I have to say is that the sql file that I want to update comes from another server where this table has the same name and structure as "storage".
What I want is to append the new entries that are in the sql file to the one in my datebase. I do not want to overwrite them.
The structure in the two tables is exactly the same. I use the Backup datebase as the name says for backup uses, so that from time to time I can backup my data.
Has anyone an idea how to solve this?
Look in the .sql file you're reading with the SOURCE command, and remove the DROP TABLE and CREATE TABLE statements that appear there. They are the cause of your table being overwritten; what's actually happening is that the table is being replaced.
You could also look into using SELECT ... INTO OUTFILE and LOAD DATA INFILE as a faster and less potentially destructive way to get data from one server to the other in a file.
I have 100+ XLSX files that I need to get into a MySQL Database. Each file is a bit different, so I've created a massive table that contains a field for each possible column header across all files. This way they can auto-map on import.
Using Navicat I can import the files one at a time, but I'm wondering if there is a way to import all of the files at one time?
I'm thinking 'no' but if your going to do this a lot I think there are ways to automate this.
Export your xls-files into csv-files instead. Write some script to transform them between csv-excel style to csv-mysql style.
Create tables for importing with the csv engine. Put your files inplace of the ones created by mysql and flush tables. Now your data is ready to be read inside mysql and copied over to more powerful tables engines.
Another way is to do a VBA-script that exports the data in a format recognized by load data infile and then load them using mysql.
