  • How to crosscheck two tables and insert relevant data into a new table in MYSQL?

    - by JackDamery
    I'm trying to crosscheck a row that exists in two tables using a MYSQL query in phpmyadmin and then if a userID is found in both tables, insert their userID and user name into another table. Here's my code: INSERT INTO userswithoutmeetings SELECT user.userID IF('user.userID'='meeting.userID'); I keep getting plagued by this error: 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IF('user.userID'='meeting.userID')' at line 3 Other statements I've tried have worked but not deposited the values in the table.

  • Google sheet dynamic WHERE clause for query() statement

    - by jason_cant_code
    I have a data table like so: a 1 a 2 b 3 b 4 c 5 c 6 c 7 I want to pull items out of this table by dynamically telling it what letters to pull. My current formula is: =query(A1:B7,"select * where A ='" & D1 & "'"). D1 being the cell I wish to modify to modify the query. I want to be able input into D1 -- a, a,b, a,b,c and have the query work. I know it would involve or statements in the query, but haven't figured out how to make the formula dynamic. I am looking for a general solution for this pattern: a -- A = 'a' a,b -- A = 'a' or A = 'b' a,b,c -- A = 'a' or A = 'b' or A='c' Or any other solution that solves the problem. Edit: So far I have =ArrayFormula(CONCATENATE("A='"&split(D3,",")&"' or ")) this gives A='a' or A='b' or A='c' or for a,b,c. can't figure out how to remove the last or.

  • Prioritize SQL WHERE clause

    - by JaTochNietDan
    Basically I want to do this: SELECT * FROM `table` WHERE x = 'hello' OR x = 'bye' LIMIT 1'; I want it to return 1 value, but to prioritize results from the 1st where clause. So if there exists a row where column x's value is "hello", it will not return the result from the 'bye' value. If the "hello" value doesn't exist though, it will return the result from the 'bye' value. Can't figure out a way to do it even though it seems fairly trivial. Any ideas?

Am I making any mistake. Thanks

  • PHP - if == not working for 0 or ""

    - by user2933212
    I am checking the validation of the request with an if query, if ($request_userid == $userid) { ... } Thats working as expected. But further testing has shown, that if $request_userid or $userid is 0 or "", then the condition is true and the script runs the if query but it shouldn't. I am currently solving it with: if ($userid == "" ) { exit ("exit"); } But I don't think that this is the right way? Can you explain why it doesn’t work with the if query and what would be the correct way to check it?

  • If there's no problem treating a statement as an expression, why was there a distinction in the first place in some programming languages?

    - by cdmckay
    Why do we have the distinction between statements and expressions in most programming languages? For example, in Java, assuming f and g return ints, this still won't compile because it's a statement and statements don't return values. // won't compile int i = if (pred) { f(x); } else { g(x); } but in Scala, it's very happy with treating if as an expression. // compiles fine val i: Int = if (pred) f(x) else g(x) So if there's no problem treating an if statement as an expression, why was there a distinction in the first place?

  • Single statement if block - braces or no? [on hold]

    - by Zannjaminderson
    Which is better/more generally accepted? This: if(condition) { statement; } Or: if(condition) statement; I tend to prefer the first one, because I think it makes it easier to tell what actually belongs in the if block, it saves others from adding the braces later (or creating a bug by forgetting to), and it makes all your if statements uniform instead of some with braces and some without. The second one, however, is still syntactically correct and definitely more compact. I'm curious to see which is more generally preferred by others though.

  • Does the order of case in Switch statement can vary the performance?

    - by Bipul
    Let say I have a switch statement as below Switch(alphabet){ case "f": //do something break; case "c": //do something break; case "a": //do something break; case "e": //do something break; } Now suppose I know that the frequency of having Alphabet e is highest followed by a, c and f respectively. So, I just restructured the case statement order and made them as follows. Switch(alphabet){ case "e": //do something break; case "a": //do something break; case "c": //do something break; case "f": //do something break; } Will the second Switch statement better perform(means faster) than the first switch statement? If yes and if in my program I need to call this switch statement say many times, will that be a substantial improvement? Or if not in any how can I use my frequency knowledge to improve the performance? Thanks

  • Why are Pascal control structures inconsistent?

    - by 70Mike
    Most Pascal control structures make sense to me, like: for ... do {statement}; if (condition) then {statement}; while (condition) do {statement}; where the {statement} is either a single statement, or a begin ... end block. I have a problem with: repeat {statement-list} until (expression); try {statement-list} except {statement-list} end; Wouldn't it be better that repeat and try have the same general structure, accepting only a single statement or a begin ... end block, instead of having a statement-list that's not formally blocked with a begin and an end?

  • SQL Server 2008 Dead lock issue

    - by user173552
    I got into a deadlock issue where I am struggling find the root-cause...The Deadlock graph suggests that an UPDATE statement became the victim over a SELECT statement... What puzzles me is that the UPDATE statement is trying to acquire an index on some other table that is never referred in update statement... This is how my UPDATE statement looks like... UPDATE Table set col1 = @P1 where col2 = @P2 This statement acquired a X lock on the col2 index, but also tries to acquire an index on a column defined in some other table that is no way related to the UPDATE statement... And the SELECT statement that won the deadlock situation had nothing to do with the table or index in the update statement but tried to acquire an index on the table in UPDATE statement. eventually causing the DEADLOCK.
