Grant read write access sql if statement

NET assemblies in the database, while prior versions of SQL Server were restricted to unmanaged extended stored procedures primarily written in C. In particular date and time syntax, string concatenation, NULLs, and comparison case sensitivity vary from vendor to vendor. The folding of unquoted names to lower case in PostgreSQL is incompatible with the SQL standard, [25] which says that unquoted names should be folded to upper case. As a result, SQL code can rarely be ported between database systems without modifications.

The ARN value specified in the Resource identifies a table in a specific region. Carefully consider the security implications if you decide to do this.

Set Up Permissions Policies for Separate Test and Production Environments Suppose you have separate test and production environments where each environment maintains its own version of a table named ProductCatalog.

If you create these ProductCatalog tables from the same AWS account, testing work might affect the production environment because of the way that permissions are set up for example, the limits on concurrent create and delete actions are set at the AWS account level.

As a result, each action in the test environment reduces the number of actions that are available in your production environment. There is also a risk that the code in your test environment might accidentally access tables in the production environment.

To prevent these issues, consider creating separate AWS accounts for your production and test environments. Suppose further that you have two developers, Bob and Alice, who are testing the ProductCatalog table.

Instead of creating a separate AWS account for every developer, your developers can share the same test account. You can then grant permissions to these users to perform DynamoDB actions on the tables that they own.

To grant these user permissions, you can do either of the following: Create a separate policy for each user and then attach each policy to its user separately. Instead of attaching policies to individual users, you can use IAM policy variables to write a single policy and attach it to a group. You need to create a group and, for this example, add both users Alice and user Bob to the group.

Permissions Required to Use the Amazon DynamoDB Console

The default version of the access policy language does not support policy variables. With reserved capacity, you pay a one-time upfront fee and commit to paying for a minimum usage level, at significant savings, over a period of time.

However, you might not want all of the users in your organization to have the same levels of access. DynamoDB provides the following API operations for controlling access to reserved capacity management: DescribeReservedCapacity — returns the reserved capacity purchases that are currently in effect.

DescribeReservedCapacityOfferings — returns details about the reserved capacity plans that are currently offered by AWS. PurchaseReservedCapacityOfferings — performs an actual purchase of reserved capacity.

You cannot call these operations from an application program, because they are only accessible from the Console. However, you can allow or deny access to these operations in an IAM permissions policy.

The following policy allows users to view reserved capacity offerings and current purchases using the AWS Management Console—but new purchases are denied. For example, you can configure AWS Lambda to poll the stream and invoke a Lambda function when item updates are detected, and then perform additional processing.

ADMINISTER SQL TUNING SET: Create, drop, select (read), load (write), and delete a SQL tuning set owned by the grantee through the DBMS_SQLTUNE package. Often this means your /tmp partition has run out of space and the file can't be created, or for whatever reason the mysqld process cannot write to that directory because of permission problems.

Sometimes this is the case when selinux rains on your parade.. Any operation that requites a "temp file" will go into the /tmp directory by default. The name you're seeing is just some internal random name. For some reason my production DB decided to spew out this message.

All application calls fail to the DB with the error: PreparedStatementCallback; SQL [ /*long sql statement here*/ ]; Can't create/. Administering a CDB with SQL*Plus includes tasks such as access a container in a CDB, modifying a CDB, executing DDL statements in a CDB, and running Oracle-supplied SQL scripts in a CDB.

The session that holds the lock can read and write the table. Only the session that holds the lock can access the table. No other session can access it until the lock is released.
