    <p>I am trying to update a text field. Moving data to another column and truncate because it is too long.</p> <p>The update statement looks like this. (Edited)</p> <pre><code>UPDATE Feuil1 SET [Occupant 2] = SWITCH ( [Occupant 2] IS NOT NULL, [Occupant 3], (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 3), mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 4), mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 5), mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 6), mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 7), mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 2), '', (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 1), '', [Occupant 1] LIKE '* &amp; *', mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), [Occupant 1] LIKE '* ET *', mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," "),30), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 0), '' ), [Occupant 1] = SWITCH ( (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 3), mid([Occupant 1],1,InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," ")), (LEN([Occupant 1]) - LEN(REPLACE([Occupant 1], ' ', '')) = 4), mid([Occupant 1],1,InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," ")), [Occupant 1] LIKE '* &amp; *', (replace([Occupant 1], ' &amp; ' &amp; mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," ")),InStr(InStr(2,[Occupant 1]," ")), '')), [Occupant 1] LIKE '* ET *', (replace([Occupant 1], ' &amp; ' &amp; mid([Occupant 1],InStr(InStr(1,[Occupant 1]," ")+1,[Occupant 1]," ")),InStr(InStr(2,[Occupant 1]," ")), '')) ) WHERE [Occupant 1] IS NOT NULL </code></pre> <p>I always get conversion type error but I don't know why. I am updating a text field with it's own modified data. All the columns involved are text.</p> <p>I've tried to use Val(), Cstr() functions, same result.</p> <p>Additionnal informations: Some data seems to be processed, but I can't find why.</p> <p>Any clues?</p>

    1. COThat updates 2 fields, `[Occupant 2]` and `[Occupant 1]`, using complex `Switch()` expressions. Split it into 2 separate `UPDATE` statements, each of which updates only a single column. That way at least you can determine which of the 2 `Switch()` expressions triggers the error.

    2. COIn fact, both trigger the same error. Should I use a cast that I didn't listed? I'm pretty confused right now

    3. COI got lost trying to understand those `Switch()` expressions. I suggest you try a `SELECT` query which uses them in the field list. Then you can examine their return values and hopefully identify the values which trigger the error. `SELECT DISTINCT` and `TypeName(Switch(...))` could be useful in that effort.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
