Boolean Logic question: can I coerce these 4 if statements into a single boolean statement?

fixed the issue. Will look into that further I have a boolean logic question. I have the following if statements that should be able to be coalesced into a single boolean expression. Please help. I've spent way too much time on this and I'm actually too ashamed to ask my co-workers. , Would return allowOne; do the trick?

Rails - PostgreSQL boolean where statement, ERROR: operator does not exist: boolean = integer
Date : March 29 2020, 07:55 AM
will help you I have a model that contains a boolean attribute, Member can be admin. When I create a new Team I want to set this value to true for the Member that have created that Team. When I used SQLite it worked fine. The line that causes the error looks like this: , IMHO it is just: # in team.rb
has_many :admins, -> { where(admin: true) }, through: :members, source: :user
# or if you use postgresql's boolean datatype
has_many :admins, -> { where('admin = \'t\'') }, through: :members, source: :user
def set_admin
members.first.update_attributes(admin: true) if admins.none?
end

Query returns boolean after adding "WHERE date BETWEEN" statement

Hope that helps You should print out the SQL, when you want to debug something. Your query is something like this: SELECT blood_type
WHERE date BETWEEN '". $startingdate."' AND '". $endingdate ."',
count(*) AS donor_count
FROM donors
GROUP BY blood_type;
SELECT blood_type, count(*) as donor_count
FROM donors
WHERE date BETWEEN '". $startingdate."' AND '". $endingdate ."'
GROUP BY blood_type;

SQL - Adding/Disabling a Where clause based on a boolean condition in Select Statement (ASP.net SQLDataSource)

around this issue You could do literally what you're asking (i.e. disable the where clause) using dynamic sql. declare @ssql varchar(max)
set @ssql = 'SELECT * FROM myTable'
+ CASE WHEN @parameter = 'true' THEN ' WHERE status != 5' ELSE '' END
EXEC (@ssql)
WHERE (@parameter=True AND status!=5) OR (@parameter=false)
