| Postgres to SQL Quick Tips | 3/4/2022 7:23:55 AM |
| Very First make sure your working with a great Postgres DBA.
1. Convert the schema from Postgres to SQL Server 2. Install ODBC Drivers 3. Use SSIS or it's watered down cousin DTSWizard 4. If really necessary you can drop down to custom code to transfer data. 5. Edit the ProvidersDescriptors.xml 6. Out of Memory Reading tuples ? (add UseDeclareFetch=1 to connect string).
For data type compatibility https://www.convert-in.com/docs/mss2pgs/types-mapping.htm For: sql server odbc postgres column attribute colum_size is not valid providerdescriptors.xml MaximumLengthColumnName, NumericPrecisionColumnName, and NumericScaleColumnName attribute values to "LENGTH", "PRECISION", and "SCALE", respectively.
The column attribute "COLUMN_SIZE" is not valid. The column attribute "DECIMAL_DIGITS" is not valid. The column attribute "COLUMN_SIZE" is not valid.
<dtm:ColumnSchemaAttributes
NameColumnName = "COLUMN_NAME"
OrdinalPositionColumnName="ORDINAL_POSITION"
DataTypeColumnName = "TYPE_NAME"
MaximumLengthColumnName = "COLUMN_SIZE"
NumericPrecisionColumnName = "COLUMN_SIZE"
NumericScaleColumnName = "DECIMAL_DIGITS"
NullableColumnName="NULLABLE"
NumberOfColumnRestrictions="4"
/>
... to ... <dtm:ColumnSchemaAttributes
NameColumnName = "COLUMN_NAME"
OrdinalPositionColumnName="ORDINAL_POSITION"
DataTypeColumnName = "TYPE_NAME"
MaximumLengthColumnName = "LENGTH"
NumericPrecisionColumnName = "PRECISION"
NumericScaleColumnName = "SCALE"
NullableColumnName="NULLABLE"
NumberOfColumnRestrictions="4"
/>
sql server postgresql out of memory while reading tuples
"Driver={PostgreSQL Unicode};Server=ip;Port=port;Database=db_name;Uid=user;Pwd=pass;UseDeclareFetch=1"
