Code Explanation
Language and Context
The code snippet provided appears to be written in a pseudo-code or a specific formula language used in some data platforms (e.g., Power Query M, DAX for Power BI, or a custom formula language in a business analytics tool).
Breakdown of Code Components
Conditional Check:
if [OU11 Project] = "0020" or "0021" or "0022" and [LD Financing] = null
This part of the code checks two conditions:
- Whether the value of
[OU11 Project]
is one of "0020", "0021", or "0022". - Whether the value of
[LD Financing]
isnull
(i.e., it has no value).
- Whether the value of
Result If Condition Is True:
then "Non Landbank"
This part specifies that if the above conditions are met, the resulting value should be
"Non Landbank"
.Result If Condition Is False:
else "LB"
This part specifies that if the above conditions are not met, the resulting value should be
"LB"
.
Detailed Explanation
The given code is used to determine a categorical value based on specific criteria. Here's a deconstructed explanation:
Example Context:
if [OU11 Project] = "0020" or "0021" or "0022" and [LD Financing] = null then "Non Landbank" else "LB"
This could be part of a data transformation or calculation process where you want to classify records based on their project code and financing status.
Condition Logic:
[OU11 Project]
must be either "0020", "0021", or "0022".[LD Financing]
must benull
(no financing information).- If both conditions are satisfied, the result is "Non Landbank".
- Otherwise, the result is "LB".
Common Mistake
The logic written in the original form might not work perfectly in many scenarios, such as programming languages or certain formula languages. A proper logical conjunction needs to correctly group and check each condition distinctly.
Corrected Pseudo-Code:
if ([OU11 Project] = "0020" or [OU11 Project] = "0021" or [OU11 Project] = "0022") and [LD Financing] = null then "Non Landbank" else "LB"
Equivalent Code in Different Languages:
Python Example:
# Assuming data is stored in a dictionary data = {'OU11 Project': '0020', 'LD Financing': None} if data['OU11 Project'] in ["0020", "0021", "0022"] and data['LD Financing'] is None: result = "Non Landbank" else: result = "LB"
DAX Example (used in Power BI):
Result = IF( ( [OU11 Project] = "0020" || [OU11 Project] = "0021" || [OU11 Project] = "0022" ) && ISBLANK([LD Financing]), "Non Landbank", "LB" )
Power Query M Example:
Result = if ([OU11 Project] = "0020" or [OU11 Project] = "0021" or [OU11 Project] = "0022") and ([LD Financing] = null) then "Non Landbank" else "LB"
Key Concepts:
- Conditional Statements: Used to execute different branches of code (or assign different values) based on specified conditions.
- Logical Operators:
and
: Ensures all conditions must be true.or
: Ensures at least one of the conditions must be true.
- Null Checking: Essential for ensuring that the
LD Financing
field is empty.

Description
This code snippet classifies projects based on their codes and financing status using conditional statements. It checks if specified project codes are present and if financing is null, returning "Non Landbank" or "LB" accordingly.
