how to dump a single stored procedure from a database I need to create a dump file that contains a single stored procedure from a database, not all routines.

I've tried something like this:

mysqldump -u root -pssmart --skip-triggers --no-create-info --no-data \
    --no-create-db --skip-opt test_fshop SP_ITEM_SALES_REPORT -R \
    &gt; test_fshop_routines.sql 


Here test_fshop is my DB name and SP_ITEM_SALES is my SP. I want my SP as .sql file.
BAD NEWS

You cannot use mysqldump to do this.

GOOD NEWS

You can use the mysql client. First, find out if the Stored Procedure exists. If it does, then fetch the type of Procedure it is (PROCEDURE or FUNCTION). Then, issue the SHOW CREATE for the Stored Procedure. You will have to strip the top 3 and bottom 3 lines:

DBNAME=${1}
SPNAME=${2}
SPFILE=${DBNAME}_${SPNAME}.sql
SPTEMP=${DBNAME}_${SPNAME}.tmp
MYSQL_CONN="-u... -p..."
SQLSTMT="SELECT COUNT(1) FROM mysql.proc WHERE db='${DBNAME}' AND name='${SPNAME}'"
PROC_EXISTS=`mysql ${MYSQL_CONN} -ANe"${SQLSTMT}" | awk '{print $1}'`
if [ ${PROC_EXISTS} -eq 1 ]
then
    SQLSTMT="SELECT type FROM mysql.proc WHERE db='${DBNAME}' AND name='${SPNAME}'"
    PROC_TYPE=`mysql ${MYSQL_CONN} -ANe"${SQLSTMT}" | awk '{print $1}'`
    SQLSTMT="SHOW CREATE ${PROC_TYPE} ${DBNAME}.${SPNAME}\G"
    mysql ${MYSQL_CONN} -ANe"${SQLSTMT}" &gt; ${SPFILE}

    #
    # Remove Top 3 Lines
    #
    LINECOUNT=`wc -l &lt; ${SPFILE}`
    (( LINECOUNT -= 3 ))
    tail -${LINECOUNT} &lt; ${SPFILE} &gt; ${SPTEMP}

    #
    # Remove Bottom 3 Lines
    #
    LINECOUNT=`wc -l &lt; ${SPTEMP}`
    (( LINECOUNT -= 3 ))
    head -${LINECOUNT} &lt; ${SPTEMP} &gt; ${SPFILE}
else
    echo "Stored Procedure ${DBNAME}.${SPNAME} Does Not Exist"
fi
rm -f ${SPTEMP}


Here is a sample run:

[root@***]# ./GetMyProc.sh common DMSPushers
[root@***]# cat common_DMSPushers.sql
CREATE DEFINER=`pma`@`10.%` PROCEDURE `DMSPushers`()
BEGIN

  DECLARE cntr INT DEFAULT 0;
  DECLARE dealerName VARCHAR(50);
  DECLARE dealerID INT;

  DECLARE done boolean DEFAULT false;
  DECLARE dealers CURSOR FOR SELECT bdd.dealer_id, ta.name FROM `b_dealer__dmsaccount` bdd left join t_dmsaccount ta on bdd.dmsaccount_id = ta.id where ta.dms_type = 1 order by bdd.dealer_id desc;

  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done := true;

  OPEN dealers;

  read_loop: LOOP
        FETCH dealers INTO dealerID, dealerName;
        SET cntr = cntr + 1;

    IF done OR cntr &gt; 200 THEN
      LEAVE read_loop;
    END IF;

        IF dealerID &gt; 0 AND dealerID &lt; 664 THEN
                IF dealerName IS NULL THEN
                        SET dealerName = '';
                END IF;
                SET dealerName = REPLACE(dealerName,'''','''''');

                -- Does the Database even exist???
                SET @query = CONCAT('SELECT COUNT(SCHEMA_NAME) FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMA_NAME = ''D',dealerID,''' INTO @schemaExists');
                PREPARE stmt1 FROM @query;
                EXECUTE stmt1;

                IF @schemaExists &gt; 0 THEN
                        SET @query = CONCAT('INSERT dealers_that_push (dealerID, dealerName, pushDate) SELECT ', dealerID, ',''', dealerName ,''',date FROM D',dealerID,'.contactLog where message like ''%pushed to the DMS%''');
                        PREPARE stmt1 FROM @query;
                        EXECUTE stmt1;
                END IF;

        END IF;

  END LOOP;

  CLOSE dealers;
END

GREAT NEWS

Here is a script that will dump every Stored Procedure into separate SQL files:

MYSQL_CONN="-u... -p..."
SQLSTMT="SELECT COUNT(1) FROM mysql.proc"
PROCCOUNT=`mysql ${MYSQL_CONN} -ANe"${SQLSTMT}" | awk '{print $1}'`
if [ ${PROCCOUNT} -eq 0 ] ; then exit ; fi
SPLIST=""
for DBSP in `mysql ${MYSQL_CONN} -ANe"SELECT CONCAT(type,'@',db,'.',name) FROM mysql.proc"`
do
    SPLIST="${SPLIST} ${DBSP}"
done
for TYPEDBSP in `echo "${SPLIST}"`
do
    DB=`echo "${TYPEDBSP}" | sed 's/@/ /' | sed 's/\./ /' | awk '{print $2}'`
    SP=`echo "${TYPEDBSP}" | sed 's/@/ /' | sed 's/\./ /' | awk '{print $3}'`
    SQLSTMT=`echo "SHOW CREATE ${TYPEDBSP}\G" | sed 's/@/ /'`
    SPFILE=${DB}_${SP}.sql
    SPTEMP=${DB}_${SP}.tmp
    echo Echoing ${SQLSTMT} into ${SPFILE}
    mysql ${MYSQL_CONN} -ANe"${SQLSTMT}" &gt; ${SPFILE}
    #
    # Remove Top 3 Lines
    #
    LINECOUNT=`wc -l &lt; ${SPFILE}`
    (( LINECOUNT -= 3 ))
    tail -${LINECOUNT} &lt; ${SPFILE} &gt; ${SPTEMP}
    #
    # Remove Bottom 3 Lines
    #
    LINECOUNT=`wc -l &lt; ${SPTEMP}`
    (( LINECOUNT -= 3 ))
    head -${LINECOUNT} &lt; ${SPTEMP} &gt; ${SPFILE}
    rm -f ${SPTEMP}
done
ls -l


Give it a Try !!!
