ctGetCurrentSequenceValue
Declaration
NINT ctGetCurrentSequenceValue(LONG seqhnd, pLONG8 pcurval, pNINT punkval);
Description
Reads the current value for the specified sequence. The current value of a sequence can be one of the following:
Sequence values are stored in the database in which they are defined, and persist between each call to the ctSetCurrentSequenceValue() or ctGetNextSequenceValue() function.
Return Values
Value |
Symbolic Constant |
Explanation |
---|---|---|
0 |
NO_ERROR |
Successfully created the sequence. |
900 |
SEQDUP_ERR |
A sequence having the specified name already exists. |
903 |
SEQTYP_ERR |
The specified sequence type contains an invalid combination of sequence type options. |
904 |
SEQINI_ERR |
The initial value specified for the sequence is out of range. |
905 |
SEQCUR_ERR |
The current value specified for the sequence is out of range. |
906 |
SEQLIM_ERR |
The limit value specified for the sequence is out of range. |
907 |
SEQINC_ERR |
The increment value specified for the sequence is out of range. |
901 |
SEQNAM_ERR |
An invalid sequence name was specified: the name is NULL, empty, or too long. |
See c-treeACE Error Codes for a complete listing of valid error values.
Example
ctSEQATTR seqattr;
NINT rc;
/*
** Create an incrementing sequence that starts with 1, increments by 3, and
** terminates with 100.
*/

seqattr.seqini = 1;
seqattr.seqinc = 3;
seqattr.seqlim = 100;
seqattr.seqtyp = ctSEQINC | ctSEQTRM | ctSEQLIM;
if ((rc = ctCreateSequence(&seqattr))) {
printf("Error: Failed to create the sequence: %d\n", rc);
} else {
printf("Successfully created the sequence.\n");
