INSERT SELECT statement "Internal error - sql_select_into_memvar()"

Hi all, I hope this is the correct subforum.

I'm trying to copy the contents of one database into another. I am using javascript,the exact code is:

Code:

---

Lianja.execute("INSERT INTO table1 SELECT * FROM table2

---

Table2 has been created by invoking the "COPY STRUCTURE" command on table 1, so the structures are exactly the same. This methodology works in another app I built (different database), adding to the strangeness. When I attempt to use this command in my current app, though, I see the error mentioned in the title in the console. The error is called on the last field in the table. I even rebuilt the entire database from scratch in Lianja - it was originally imported - and STILL get the same error.

Further info:

• When I replace table2 with table1 in the code, thus copying from itself, it still spits out the same error
• Using INSERT-VALUES on these tables works totally fine
• using SELECT on these tables by itself works totally fine. Using SELECT into ARRAY, however, encounters Fatal system error (sql_select_convert_row_array() column=4 type=F) on the final field.
• If I change the order of the fields in the tables, it always encounters the error on the final field.
• The error occurs on two tables in the database and on no others. I can't see anything that separates the tables that work and the ones that don't.

What's going on? I can't seem to find this error anywhere on the net.

I'm using 2.1beta1 right now for context.

Thanks for the help.

If you SET DEBUG ON then run the command additional debugging information will be written to debug.txt. Try the command in the console also.

Also let me see the table structure.

Here's the debug output, I couldn't work anything out from it:

Is there a way to export table structures from Lianja?

Hi Joanna,

The debug output helps me.

What is the exact command you are executing.

list structure

so I can see the structure if the two tables. It seems it may be when a float data type us used. I'll look into that and fix it up.

Hi Barry,

The exact command is

Code:

---

INSERT INTO expenseitem SELECT * FROM temp_expenseitem

---

The table structure is:

Expense ID:
Name: IEXPID_PK
Type: Int
Width: 4
Mandatory

Claim ID:
Name: ICLAIMID_FK
Type: Int
Width: 4
Mandatory

Item:
Name: CITEM
Type: Character
Width: 10

Quantity:
Name: IQUANTITY
Type: Int
Width: 4
Mandatory

Price:
Name: FPRICE
Type: Float
Width: 6
Decimals: 2
Mandatory

The temp database is exactly the same structure as discussed in the original post. You may be on to something with the Float type, the only other table in my database with a float field is also the only other table that causes this error.

Ok i'll take a look. I think float is not being handled properly.

I have fixed this in v2.1Beta5 which I will upload today.
