I have a large table with existing data. The joining key/column is "UserID" (varchar)I want to insert a record in this table but for each UserID found in the tablehow can I do this?There are multiple single userID's in there, each with a different column value which is linked to another table (think of it as a joining reference table for settings for each user)any ideas? |

I did not quite follow what you meant by groups - if the data for a given userid already exists, don't you want to do an update rather than insert duplicate rows for the same userid? Can you post the schema for the two (or more tables) that are involved along with some sample data? |

Sounds like OP wants to replicate some data for each of existing users but add only once per user. Seems like currently table is having multiple records per user.If thats the case, it should be something likeINSERT INTO YourTable (UserID,.. other columns)SELECT UserID,value1,value2,..FROm (SELECT DISTINCT USerID FROM YourTable)t if this was not your question then please post some sample data as James suggested as we cant make out much from your current explanation.------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/ |

If I am not wrong, you wanted to lookup for userid's existing on other table in your join condition and for each userid it matched, you wanted to insert values. Let us know in detail. |
