Locations for simple-large-object data
Before your program accesses a simple-large-object column, it must determine where the simple-large-object data is located.
To specify whether the simple large object is located
in memory or in a file, specify the contents of the loc_loctype field
of the locator structure. The following table shows the possible locations
for simple-large-object data.
| Value of loc_loctype field | Location of simple-large-object data | See |
|---|---|---|
| LOCMEMORY | In memory | ids_esqlc_0203.html#ids_esqlc_0203 |
| LOCFILE | In an open file | ids_esqlc_0212.html#ids_esqlc_0212 |
| LOCFNAME | In a named file | ids_esqlc_0215.html#ids_esqlc_0215 |
| LOCUSER | At a user-defined location | ids_esqlc_0218.html#ids_esqlc_0218 |
Set loc_loctype after you declare the locator variable and before this declared variable receives a simple-large-object value.
The locator.h header file defines the LOCMEMORY, LOCFILE, LOCFNAME, and LOCUSER location constants. In your program, use these constant names rather than their constant values when you assign values to loc_loctype.
In a client-server environment, locates the simple large object on the client computer (the computer on which the application runs).
