# 4d-plugin-mdb

status:=mdb sql(path;sql)
```
Parameter|Type|Description
------------|------------|----
path|Text|POSIX path

the generated file follows the `SQL EXPORT SELECTION` output format:
* large Blob goes to ./BLOBS/Blob0.BLOB
* large Picture goes to ./BLOBS/{name.extension}
* main SQL
* table/field names are escaped
* Date includes default time
* Null is `NULL`
* Boolean is `0` or `1`
* Text is single quoted; single quotes are prefixed by an extra single quote; `\r\t\n\"\\` are exported raw
* small Blobs & Pictures are exported as hex e.g. `X'01020304'`
```sql
INSERT INTO [Table_1] ( [Id] , [Field_2] , [Field_3] , [Field_4] , [Field_5] )
VALUES (1 , INFILE 'BLOBS/Blob0.BLOB' , '2024/05/17 00:00:00:00' , '''abcd', INFILE 'BLOBS/Pic0.tif'),
(2 , INFILE 'BLOBS/Blob1.BLOB' , '2024/05/17 00:00:00:00' , '''efgh', X'54435034080000000000');
```
except, binary fields (`MDB_OLE` `MDB_BINARY` `MDB_REPID`) are always exported as hex.
