| Table [A] | Table [B]
| id value data | id value data
| ab 15 100 | ac 19 200
| ab 18 101 | ac 28 310
| ab 22 199 | ac 39 401
Table A is my old database table with history data. Table B is my current database table with corrected value in id
I'll like to insert historic data from Table A into Table B WHERE value<=xxxx AND value >=xxxx and also at the same time set the data from tablea.id = ac when inserted into Table B so the data outcome will be.
| Table [A] | Table [B]
| id value data | id value data
| ab 15 100 | ac 19 200
| ab 18 101 | ac 28 310
| ab 22 199 | ac 39 401
| | ac 15 100
| | ac 28 101
| | ac 22 199
I'll be using INSERT IGNORE as my table has 3 column as it's composite primary key. Table description is just a sample. My table has alot more columns just highlighting the main difference for the data import I want to accomplish.
