.SH "NAME"
MOVE \- position a cursor
.SH "SYNOPSIS"
.sp
.nf
MOVE [ \fIdirection\fR ] [ FROM | IN ] \fIcursor_name\fR
where \fIdirection\fR can be one of:
NEXT
PRIOR
FIRST
LAST
ABSOLUTE \fIcount\fR
RELATIVE \fIcount\fR
\fIcount\fR
ALL
FORWARD
FORWARD \fIcount\fR
FORWARD ALL
BACKWARD
BACKWARD \fIcount\fR
BACKWARD ALL
.fi
.SH "DESCRIPTION"
.PP
\fBMOVE\fR
repositions a cursor without retrieving any data\&.
\fBMOVE\fR
works exactly like the
\fBFETCH\fR
command, except it only positions the cursor and does not return rows\&.
.PP
The parameters for the
\fBMOVE\fR
command are identical to those of the
\fBFETCH\fR
command; refer to
\fBFETCH\fR(7)
for details on syntax and usage\&.
.SH "OUTPUTS"
.PP
On successful completion, a
\fBMOVE\fR
command returns a command tag of the form
.sp
.if n \{\
.RS 4
.\}
.nf
MOVE \fIcount\fR
.fi
.if n \{\
.RE
.\}
.sp
The
\fIcount\fR
is the number of rows that a
\fBFETCH\fR
command with the same parameters would have returned (possibly zero)\&.
.SH "EXAMPLES"
.sp
.if n \{\
.RS 4
.\}
.nf
BEGIN WORK;
DECLARE liahona CURSOR FOR SELECT * FROM films;
\-\- Skip the first 5 rows:
MOVE FORWARD 5 IN liahona;
MOVE 5
\-\- Fetch the 6th row from the cursor liahona:
FETCH 1 FROM liahona;
code | title | did | date_prod | kind | len
\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-+\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-
P_303 | 48 Hrs | 103 | 1982\-10\-22 | Action | 01:37
(1 row)
\-\- Close the cursor liahona and end the transaction:
CLOSE liahona;
COMMIT WORK;
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
There is no
\fBMOVE\fR
statement in the SQL standard\&.
.SH "SEE ALSO"
\fBCLOSE\fR(7), \fBDECLARE\fR(7), \fBFETCH\fR(7)
