File and Object Level Breakdown - SQL Identified Objects

This section shows the conversion summary for each top-level object type supported by SnowConvert

This is a deprecated version of the SnowConvert documentation, please visit the official site HERE.

Conversion Rate - Object

An object is considered successfully migrated if it does not have issues with medium, high or critical severity.

Represents the percentage of identified objects by SnowConvert that were successfully migrated. This will help to determine the number of objects that were successfully migrated and the objects that need manual work in order to complete the migration of the objects to Snowflake. If N/A is listed in the column, it means that the object type is not supported in Snowflake. A "-" could also be listed in this column, this means that the set of files migrated by SnowConvert did not contain objects of the specific type that could be identified.

Formula

(successfully_converted_objects / total_object_quantity) * 100

Sample

-- Table that is migrated successfully to Snowflake.
CREATE TABLE table1 (
  col1 INTEGER
);

-- Table that is not migrated successfully to Snowflake because of the data type of col1.
CREATE TABLE table2 (
  col1 ANYTYPE
);

Expected Object Conversion Rate: 50%

Explanation: With the previous sample code we will have a 50% Object Conversion Rate because only 1 of the 2 identified tables were successfully migrated to Snowflake.

Conversion Rate - Code

Represents the percentage of lines or characters of code of the top-level object that were successfully migrated. You can read more about the different conversion rate modes and how they are calculated by SnowConvert here.

CSV Associated Field Names

Each top-level object will have two fields for the code conversion rate in the Assessment.csv report. One will be for the conversion rate using lines of code and the other using the characters.

Sample

CREATE TABLE table1 (
  col1 INTEGER
);
CREATE TABLE table2 (
  col1 ANYTYPE
);

Expected Code Conversion Rate: 83.33%

Explanation: In the previous sample code, there are two CREATE TABLE statements and SnowConvert is executed using lines of code to calculate the code conversion rate. table1 was successfully migrated but table2 was not migrated completely, in this case, line 5 of the input code could not be migrated and only 5 of the 6 total lines of code were migrated successfully. This calculation will generate a conversion rate for tables of 83.33%.

Lines of Code

Represents the total amount of lines code used for the identified top-level objects. It is important to take into account that the lines of code of the top-level object as well as the comments are used for this column. On the other hand, empty lines will not be counted in this column.

Sample

-- Hello World

CREATE TABLE table2 (

Expected Lines of Code: 8

Explanation: In this case, we have 6 lines that come from the code used for the CREATE TABLE statements and 2 for comments that are inside of the top-level objects.

Total Object Quantity

Represents the total amount of objects identified by SnowConvert during the parsing phase.

Sample 

-- Successfully parsed table.
CREATE TABLE table1 (

);

-- Table with a parsing error that could not be identified.
CRATE TABLE table2 (
  col1 INTEGER
);

Expected Total Object Quantity: 1.

Explanation: One table was completely parsed by SnowConvert during the parsing phase but the other table has a parsing error that causes SnowConvert to not identify it as a table object.

Parsing Errors

Represents the number of parsing errors that are inside of the identified objects of each top-level object type.

-- Table with parsing error but still was identified by SnowConvert.
CREATE TABLE table1 (
  col3 NUMBER,
);

-- Table with parsing error but was not identified by SnowConvert.
CRATE TABLE table2 (
  col1 INTEGER
);

Expected Parsing Errors: 1

Explanation: Only one parsing error will be reported in the Parsing Errors column because SnowConvert was able to only identify the first table. Since the second table was not identified, those parsing errors will not be counted in the Parsing Errors column.
