Reduces a number to the specified
places
|
truncate(9.22, 1) = 9.2
truncate(9.28, 1) = 9.2
|
|
Beas also permits the use of logical formulas with the following structure:
if ( logic , value by true , value by false)
e.g.
if ( red = blue , 3.34 * x , 0 ) + (x * 2)
Logical characters and functions
=
|
Both values are identical
|
Price = 100
|
>
|
Left value greater than right value
|
Price > 100
|
<
|
Left value smaller than right value
|
Price < 100
|
<>
|
Left value is not right value
|
Price <> 100
|
>=
|
Left value greater than or equal
to right value
|
Price >= 100
|
<=
|
Left value smaller than or equal
to right value
|
price <= 100
|
NOT=
|
Left value is not right value
|
Price not = 100
|
LIKE
|
Left value is part of right value
|
Name like 'C%'
|
IN
|
Left value contained in right list
|
Price in (100,200,300)
|
BETWEEN
|
Left value is in the range of
|
Price between 1000 and 2000
|
NOT LIKE
|
Left value is not in right value
|
Price not like 'C%'
|
NOT IN
|
Left value is not in right list
|
Price not in (100,200,300)
|
NOT BETWEEN
|
Left value is not in range
|
Price not between 1000 and 2000
|
LIKE works with placeholders:
% Any number of characters
_ Any single character
Example:
'c%' corresponds to any string beginning with c
'c_' corresponds to any string beginning with c and containing one additional arbitrary character
|
Conditions can be linked with AND and OR as well as with NOT AND/OR:
if ( x = y and x = z ,1,0)
if ( x = y or x = z,1,0)
if ( x = y and not x = z,1,0)
|
 Logical formulas with "case"
With case different results can be returned depending on a condition.
case ( column when value1 then result1 { when value2 then result2
{ ... } } { else resultelse } )
case (marriage_status when 'S' then 'Single' when 'M' then 'Married' else 'Unknown')
|
Characters can be processed.
Characters are combined through +
a = "Adam"
b = "Eve"
a + " " + b = "Adam Eve"
Beginning and end of a string must be identified.
The following are permitted as identifier fields:
" "Hello World"
' 'Hello World'
[.] [Hello World]
The use of identifier fields in string fields is permitted if the string begins with a different identifier field:
"[Hello] 'World'" Result: [Hello] 'World'
