where-clause

I'm having trouble crafting a fairly simple query with Doctrine... I have two arrays ($countries, $cities) and I need to check whether database record values would match any inside either. I'm looking for something like: ->whereIn('country', 'city', $countries, $cities) ... with 'country' being a WHERE IN for $countries and 'city' being a WHERE IN for $city. I could separate the two out but the needed query has lots of other conditions so that's not possible. The resulting SQL I'm after would be: SELECT ... WHERE ... AND ... AND ... AND ('country' IN (1,2,3) OR 'city' IN (7,8,9)) AND ... AND .

I've been battling this one for a while now. I have a stored proc that takes in 3 parameters that are used to filter. If a specific value is passed in, I want to filter on that. If -1 is passed in, give me all. I've tried it the following two ways: First way: SELECT field1, field2...etc FROM my_view WHERE parm1 = CASE WHEN @PARM1= -1 THEN parm1 ELSE @PARM1 END AND parm2 = CASE WHEN @PARM2 = -1 THEN parm2 ELSE @PARM2 END AND parm3 = CASE WHEN @PARM3 = -1 THEN parm3 ELSE @PARM3 END Second Way: SELECT field1, field2...etc FROM my_view WHERE (@PARM1 = -1 OR parm1 = @PARM1) AND (@PARM2 = -1 OR

I have an SQL question which may be basic to some but is confusing me. Here is an example of column names for a table 'Person': PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood Let's say that I input the row: 121312, Rayna, Pieterson, BMW123d, Brown, NULL, NULL Now I want to update the values for this person, but only if the new value is not null, Update: 121312, Rayna, Pieterson, NULL, Blonde, Fanta, NULL The new row needs to be: 121312, Rayna, Pieterson, BMW123d, Blonde, Fanta, NULL So I was thinking something along the lines of: Update Person(PersonalID, FirstName,

I'm struggling with a join/where clause with what is a rather simple sql select statement. I am trying to retrieve a list of product information from tb1 with the where condition behind situated in tbl2 but this must be joined by three different columns. so the SQL would look something along the lines of: SELECT tb1.* FROM tb2 INNER JOIN tb1 ON tb2.Col1 = tb1. Col1 AND tb2.Col2 = tb1. Col2 AND tb2.Col3 = tb1.Col3 WHERE (tb2.Col1 = col1) AND (tb2.Col2 = col2) AND (tb2.Col4 = string) ColX is the main where clause with the string to be passed in as parameter; all other columns are within the

I need to have a conditional where clause that operates as so: Select * From Table If (@booleanResult) Begin Where Column1 = 'value1' End Else Begin Where column1 = 'value1' and column2 = 'value2' End Any help would be appreciated. Could you just do the following? SELECT * FROM Table WHERE (@booleanResult = 1 AND Column1 = 'value1') OR (@booleanResult = 0 AND Column1 = 'value1' AND Column2 = 'value2') You can group conditions easily in a WHERE clause: WHERE (@BooleanResult=1 AND Column1 = 'value1') OR (@BooleanResult=0 AND Column1 = 'value1' AND column2 = 'value2') Based on the script in

I'm developing a web API with Laravel 5.0 but I'm not sure about a specific query I'm trying to build. My classes are as follows: class Event extends Model { protected $table = 'events'; public $timestamps = false; public function participants() { return $this->hasMany('App\Participant', 'IDEvent', 'ID'); } public function owner() { return $this->hasOne('App\User', 'ID', 'IDOwner'); } } and class Participant extends Model { protected $table = 'participants'; public $timestamps = false; public function user() { return $this->belongTo('App\User', 'IDUser', 'ID'); } public function event() {
