Mysql updating a table from another table Sex open girl chate

I thought the following commandwould work but I keep getting "unknown table masterfolder in field list". If IGNORE is provided, all errors encountered during the update are ignored.But the 2nd Where clause simply return the message of `more than one row is return', since the id is unpredictable and this create a `many to many' relationship in both tables. Many Thanks, (script) REM* the where-clause of the update cannot work UPDATE table b SET column_b1 = ( SELECT MAX(column_a1) FROM table_a a, table_b b WHERE a.id=GROUP BY a.id) WHERE table_IN (SELECT MIN(id) FROM table_a GROUP BY id); Your example is somewhat confusing -- you ask "update column a1 in table a where data in column b1 in table b" but your update shows you updating column b1 in table B with some data from table a. Every month the client office is to give data(NEW & EDITED) "BY DATE RANGWISE" to the headoffice in CD. Now, you "two step" it: insert into gtt select b.id, count(*) cnt from tabb b, taba a where = and a.cycle = b.cycle and b.site_id = 44 and b.rel_cd in ( 'code1', 'code2', 'code3' ) and b.groupid = '123' and is null group by / that gets all of the id/cnts for only the rows of interest.Additionally -- given the way the where and set clauses are CODED in the above -- it would succeed. The Headoffice is merge the data into their system. For migration data first of all i create another temporary user named VISTEMP then cotinuing this kinds of code insert into VISTEMP. Now we can update the join: update ( select a.pop, from taba a, gtt b where = ) set pop = cnt / and thats it. Hi Tom, I’m selecting approximately 1 million records from some tables and populating another set of tables.If you access a column from the table to be updated in an expression, assignments are generally evaluated from left to right.

Phone_book ---- ------ -------------- | id | name | phone_number | ---- ------ -------------- | 1 | John | 111111111111 | ---- ------ -------------- | 2 | Jane | 222222222222 | ---- ------ -------------- Call ---- ------ -------------- | id | date | phone_number | ---- ------ -------------- | 1 | 0945 | 111111111111 | ---- ------ -------------- | 2 | 0950 | 222222222222 | ---- ------ -------------- | 3 | 1045 | 333333333333 | ---- ------ -------------- There's several different ways of doing this, with varying efficiency, depending on how good your query optimiser is, and the relative size of your two tables: This is the shortest statement, and may be quickest if your phone book is very short: Should remove the subquery, allowing the query optimiser to work it's magic.The query would in fact execute without any error messages since the correlated subquery in SET clause returns EXACTLY one row for each row in B and the where clause executes without error. Lets say you have a table A ( id int, a1 varchar2(25) ) and a table B ( id int PRIMARY KEY, b1 varchar2(25) ). REGISTRATION(BIN, NAME, NAME_ALIAS, COR_GROUP, AUTHOBY, AUTHODATE, CG_NAME, ADD1, ADD2, ADD3, TEL1, FAX1, ADD5, ADD6, ADD7, TEL2, FAX2, ADD9, ADD10, ADD11, TEL3, FAX3, TP_TYPE, TRD_LINC, TRD_FY, TRD_AUTH, IMP_REG, EXP_REG, REG_TYPE, TIN, STATUS, PRE_BIN, DATREG, STAT_CHNG, ACT_CODE, ACT_MULT, ITEM_TYPE, OLD_ACT, APP_CAT, LCODE, ISSUE_DATE, VREG, M_POSI, MFUNC, SFUNC, LAST_USER, LAST_ACCS, TREG, PAY_FREQ, CREG, EREG, OREG, OP_BAL, OP_BAL_DT) select BIN, NAME---- from VIS. Thank u very much for ur kind & very helpful reply. Here the source tables have data with leading spaces and the target data should be without spaces.I put a primary key on B(id) because if there is NO SUCH constraint -- the update is totally ambigous -- if there is more then 1 value of B1 in B for a given ID -- we cannot tell what row in B should be used to update the row in A. REGISTRATION where BIN NOT IN (select BIN from VIS. Its working very nicely.i will greateful to u forever.i was suffering by this problem for a long i am using the following / insert into VISTEMP. i could envision problems with only a second of granularity on a clock -- you could miss a record or two due to that. d) I don't program forms -- you can try otn.- Thank u very much for ur nice reply. I plan to use RTRIM function in the WHERE clause to get specific set records and then after fetching, I’ll insert with a RTRIM on each column.This option takes a list of one or more partitions or subpartitions (or both).Only the partitions (or subpartitions) listed are checked for matches, and a row that is not in any of these partitions or subpartitions is not updated, whether it satisfies the clause, are flagged as unsafe for statement-based replication.

    They're lucky kids, to be surrounded by so much love. That is what I want to model now, because that is what I want for YOU: I want you to grow so comfortable in your own being, your own skin, your own knowing - that you become more interested in your own joy and freedom and integrity than in what others think about you. What I need you to know- and what I know you need to know- is that I am deeply, finally, FINE.
