Updating using 2 tables with sql
Besides being time-consuming, you are likely to make mistakes.
To simplify syntax, T2 is an alias name for Table2, whose rows we want to update based on matching rows with Table1.
The article Excel Connect To External Data (Access Database) describes the process in detail. It indicates pessimistic locking, record by record.
Step 2: Create a new recordset that will store the data from the table, “Product Table", in our case. When you use a keyset cursor you can’t see records that other users add, although records that other users delete are inaccessible from your Recordset. The provider does what is necessary to ensure successful editing of the records, usually by locking records at the data source immediately after editing.
Inner join is used to select rows from multiple tables based on a matching column in one or more tables.
It compares each row value of a table with each row value of another table to find equal values.
