24 | | -* Snowflake: Improved performance on write (#760). |
| 18 | +* Improved argument checking and transitioned to the cli package for |

| 24 | + |
26 | 25 | * Adjusted the default `batch_rows` value for `dbWriteTable()` and `dbBind()` |
27 | 26 | methods. odbc 1.3.0 changed the default value from 1024 to `NA`, which sets the |
28 | 27 | batch size to be the length of the input. While this addressed issues for |
|
31 | 30 | drivers. The package will now interpet `NA` as the minimum of 1024 and the |
32 | 31 | length of the input (@simonpcouch, #774). |

34 | | -* odbc now always converts the encoding of non-ASCII column names of the SQL |

38 | | - of client and db-server are different. (@shrektan, #432) |

42 | 41 | * Transitioned `odbcDataType()` to use S4 for consistency. S3 methods defined |
43 | | - locally will need to be rewritten (#701). |

| 42 | + locally will need to be rewritten (@simonpcouch, #701). |
46 | 43 |
|
47 | 44 | * The `"OdbcConnection"` method for `dbQuoteIdentifier()` will no longer |
48 | 45 | pass `x` to `encodeString()` before returning, for consistency with the |
49 | 46 | default implementation in DBI (@simonpcouch, #765). |
50 | 47 |
|
51 | | -* `odbc::databricks()` now picks up on Posit Workbench-managed Databricks |
| 48 | +* A bug in the implementation of a new feature introduced in 1.4.2, where the |
| 49 | + package would automatically set the `ODBCSYSINI` environmental variable when |
| 50 | + using the unixODBC driver manager, was fixed; that environmental variable |
| 51 | + will now actually be set on package load (@simonpcouch, #792). |

52 | 59 | credentials when rendering Quarto and RMarkdown documents in RStudio |

211 | 223 | * When calling `sqlCreateTable(con, ..., temporary = TRUE)` and `con` is a |
212 | 224 | connection of class `DB2/AIX64`, the `CREATE TABLE` statement that is generated |
213 | 225 | properly creates a temporary table in DB2. The statement begins with |
214 | | - [`DECLARE GLOBAL TEMPORARY TABLE`](https://www.ibm.com/docs/SSEPEK_11.0.0/sqlref/src/tpc/db2z_sql_declareglobaltemptable.html) |
| 226 | + `DECLARE GLOBAL TEMPORARY TABLE` at |
| 227 | + `https://www.ibm.com/docs/SSEPEK_11.0.0/sqlref/src/tpc/db2z_sql_declareglobaltemptable.html` |
215 | 228 | and ends with `ON COMMIT PRESERVE ROWS` (DB2's default behavior is |
216 | 229 | `ON COMMIT DELETE ROWS`, which results in the inserted data being |
217 | 230 | deleted as soon as `dbWriteTable` completes). (@rnorberg, #426) |
